SURFACE TREATMENT METAL POWDER, CONDUCTIVE PASTE USING SAME, AND PRINTED WIRING BOARD AND CHIP COMPONENTS OBTAINED BY USING CONDUCTIVE PASTE

摘要

PROBLEM TO BE SOLVED: To provide metal powder with which conductive paste doing without a viscosity adjustment as far as possible can be obtained and the conductive paste. SOLUTION: A surface treatment layer that surface treatment metal powder is equipped with on the powder surface is formed of an organic compound having both an acid radical and a base. The organic compound having the both acid radical and base has an acid number within the range of 10(KOHmg/g) to 110(KOHmg/g), and an amine value within the range of 15(KOHmg/g) to 150(KOHmg/g).
