CONDUCTIVE MEMBER FOR FILLING UP THROUGH HOLE

摘要

PROBLEM TO BE SOLVED: To provide a conductive member which fills up a through hole without causing wear nor generating voids and has good conductivity, and to provide a wiring board using the member. SOLUTION: This conductive member for filling up through hole is prepared by mixing (b) a metal having a low melting point of <=300 deg.C and (c) metal powder in (a) a substrate composed of a thermoplastic resin or thermoplastic elastomer, and their mixture.
