PURPOSE: To enable the rapid bending of the lead of electronic parts to a desired shape by rapidly and exactly judging whether the lead is inserted to the prescribed position on a substrate or not.

CONSTITUTION: This lead bender for the electronic parts consists of a pedestal 22 which is provided in the projecting direction of the lead L of the substrate S, a moving body 23 which is provided on the pedestal 22 and is freely movable forward and backward along one direction of the plane of the substrate S, a bending member 25 which is provided relatively displaceably with the moving body 23 and bends the lead L of the electronic parts and a detecting means 27 which detects the relative the moving body 23.
