The purpose of the present paper is to reveal the distribution and change of voting returns in the elections to the House of Councilors (National Constituency), and to examine the relation between the voting returns and regional socio-economic characteristics in Aichi Prefecture. For that purpose, (1) voting ratios and polls to each political party were calculated in order to examine the distribution and change of voting returns between the 7th election (1965) and the 10th election (1974), (2) factor analysis was applied to 38 variables selected for regional socio-economic characteristics and their changes in Aichi Prefecture both in 1965 and 1975, and (3) the relations between factor scores and voting returns were analysed by multiple regression analysis. The study area contains 101 wards, cities, towns and villages in Aichi Prefecture (Fig. 1).<br> The results obtained from these analyses are summarized as follows:<br> 1. In the 7th election, the voting ratio was higher in rural and mountainous areas and lower in urban areas, which was also the tendency held in the 10th election (Fig. 2-a, b). The polls of the Jimin Party (Liberal-Democratic Party, L. D. P.) were more numerous in rural and mountainous areas and less so in urban areas in the 7th election. The polls of the L. D. P, decreased in the 10th election (Fig. 2-c, d). The percentage of polls of the Shakai Party (Japan Socialist Party, J. S. P.) were higher in urban areas in the 7th election, because the J. S. P. was supported by a number of labour unions. The J. S. P.'s polls decreased, however, in urban areas in the 10th election (Fig. 2-e, f). The Komei Party, the Minsha Party (Democratic-Socialist Party, D. S. P.) and the Kyosan Party (Japan Communist Party, J. C. P.) secured more votes in urban areas than in rural and mountainous areas in the 7th election, and they received more votes from urban areas in the 10th election than in the 7th election (Fig. 2-g-1). The Komei Party and the J. C. P. won more votes in Nagoya City and its suburbs, and their polls increased there between the 7th and 10th elections. The D. S. P, is supported by such labour unions as fiber industries and the Toyota Automobile Company Ltd. and its allied companies. Therefore the D. S. P, polled more votes where those companies were located than other areas.<br> 2. Eight factors for 1965 and nine factors for 1975 were extracted by the factor analysis. Based on the eigen values above unity, the cummulative percentage to the total variance was 83.8% and 85.4% respectively (Tables 2 and 3). The maj or dimension thus extracted was employment types (38.1%) for 1965, which had high factor loading to many variables and showed general characteristics of urban-rural extent. As for 1975 some factors showing commercial activities as well as density, increase, and constitution of population had high percent of explanation. Those analyses suggest that industries have dispersed and the regional difference of the tertiary industries has become notable during ten years.<br> 3. The results of multiple regression analysis suggest that there is a close relation between the voting ratios and the socio-economic characteristics (Table 4). As to the 7th election, the voting ratios were generally explained by the first factor, while the factors to explain the 10th election's voting ratios varied greatly from one party to another. Most residuals from the multiple regression model were explained by the organized polls of labour unions especially in J. S. P. and D. S. P. and by the personal polls of influential members.
