摘要

PROBLEM TO BE SOLVED: To provide a flexible printed wiring board which is superior in adhesion property of a resin substrate and metal wiring. SOLUTION: The printed wiring board has the resin substrate having a fine concave and convex surface, a base layer formed on the fine concave and convex surface, a seed layer formed on the base layer in a pattern shape and a wiring plating layer formed on the seed layer. The base layer comprises a metal for adhesion property improvement. COPYRIGHT: (C)2007,JPO&INPIT
