Pressure measurement at the center of imploding detonation waves was carried out using a piezofilm stress gauge (PVF<SUB>2</SUB>). From the present measurement, the maximum pressures averaged within 2 and 3 mm in radius from the geometric implosion center are almost proportional to the initial pressure;P<SUB>max (r=2mm) </SUB> = P<SUB>O</SUB> × 1. 2 × 10<SUP>4</SUP> and P<SUB>max (r=3mm) </SUB> = P<SUB>O</SUB> × 9. 0 × 10<SUP>3</SUP>. The measured pressure is compared with estimated one based on the selfsimilar solution of imploding shock waves.
