<P>PROBLEM TO BE SOLVED: To provide polymer fine particles, which enables electric connection with excellent connection reliability. <P>SOLUTION: In a compression test of compressing the polymer fine particles at loading speed of 0.2275 gf/sec, the polymer fine particles exhibit a preliminary breaking behavior in which a part of the polymer fine particles preliminarily breaks, before exhibiting a breaking behavior in which the whole of polymer fine particles breaks. <P>COPYRIGHT: (C)2012,JPO&INPIT |
