  • Publication number: 20070212001
    Abstract: When a resin 59 to form a molded body 20 is poured and a lead frame 30 is attached to a front end face 21 of the molded body 20 by insert molding, protective leads 32 provided on both outsides of a lead pattern 31 of the lead frame 30 moderate the flow of the resin 59 and the force acting on the lead pattern 31 is decreased, so that misregistration of the lead pattern 31 can be prevented. Accordingly, the inserted and molded lead frame 30 can be wired on the front end face 21 of the molded body 20 for easily accomplishing three-dimensional electric wiring.
