CONDUCTIVE PASTE AND MULTILAYER WIRING BOARD USING IT

摘要

PROBLEM TO BE SOLVED: To provide conductive paste for realizing interlayer connection of high reliability without gas generation or swelling accompanying it.

SOLUTION: The conductive paste contains a conductive metal material and a resin material. The conductive metal material contains high-melting-point metal and low-melting-point metal, which latter contains Sn. The resin material contains thermoplastic polyester resin. A content of the Sn is 20% by mass to 30% by mass of the conductive metal material as a whole.
