摘要： PURPOSE:To obtain high purity uniform fine particles of a noble metal or foil having no stuck impurities with high production efficiency by capturing a noble metal evaporated by heating in a vacuum bell jar by a capturing body placed in the bell jar. CONSTITUTION:A bell jar 1 is evacuated and a noble metal 8 is evaporated by heating in the vacuum bell jar 1. The evaporated noble metal 8 is captured by the surface of a capturing body 11 placed in the bell jar 1 to form fine particles or foil. By this method, high purity uniform fine particles of a noble metal or foil having no stuck impurities is obtd. with high production efficiency.
