Abstract
An electroless plating bath composition is produced by mixing stannous oxide, at least one member selected from the group consisting of lead oxide and lead perchlorate, perchloric acid, and thiourea. The composition thus obtained is ideal for electroless plating of a substrate of copper, particularly a substrate provided with a resist film.
