Abstract

PURPOSE:To reduce an interval space between lead wires and a package in a molded type electronic device by forming a hole at the portion passing the lead wires from the package. CONSTITUTION:A hole 3 is perforated at the lead wires 2 over the outer surface of a package 1. Thus, it increases the resin self-clamping strength and decreases the cross area of the portion passing the resin with the lead wires to largely reduce the interval between the package and the lead wires. Accordingly, it can improve a moisture resistance reliability.
