  Despite numerous studies on the fluidity of molten metals, little is known on fluidity in extremely thin sections such as 0.1mm or less. The objective of this study is to find factors dominating fluidity in extremely thin sections through droplet tests of Bi metals. Pure Bi was melted and dropped onto a gap of 0.03 to 0.1mm in width. The accuracy of the gap width was ensured by inserting gap gauges between the blocks of copper, steel, or quartz. The dropping height was changed from 30 to 120mm. The movement of the molten metal in the quartz mold was directly observed by a high speed camera. The relation between the gap width of mold and flow length was linear, and flow length increased with dropping height. Direct observation, showed that metal flow was slowed down by the resistance generated by viscosity and surface tension, and was stopped by solidification. The heat transfer coefficient was estimated to be about 45 to 60 kWm<sup>-2</sup>K<sup>-1</sup>.
