Abstract

PURPOSE:To facilitate fitting to a mounting substrate with accurate positioning, by extending the projection tapered further at the top end of a plurality of staged leads projected from a package part toward the lower part. CONSTITUTION:A plurality of leads 2 are projected on the both sides of the package part 5 of a dual-in-line type IC part 1 and bent down. The lead at the joint of the package 5 has thick width to form the staged lead 3 on the narrower part continuous thereto. The narrower lead 4 is tapered with the projection 7 at the top end. Thus, the mounting substrate can be easily inserted into fitting holes for positioning.
