ABSTRACT:
An electric wire insert is first produced from a primary product 10 having support projections 13 which abut on the interior of a mold and at least one bore 12 is provided on a final portion to be a part of the exterior of a resin-molded portion 1 so that at least one of the electric wires 22 extends through the bore 12 having a slightly smaller internal diameter than the external diameter of the electric wires. After inserting a terminal-pressed electric wire 20, the primary product 10 with the terminal electric wire 20 is set and disposed in position in the mold by the support projections 13. Then, a secondary forming operation is carried out. Thus, a resin-molded product 1 is formed in which a secondary forming resin covers the exterior of the primary product 10. Since the electric wire does not come into contact with the interior of the mold because of this construction, it is possible to prevent damage due to biting of the mold and to effect an automatic setting of the electric wire in the mold by a robot.
