PROBLEM TO BE SOLVED: To position in laminating even without using a hanging pin by bringing a jig into contact with a plurality of end faces of a lead frame having a corner or a recess exposed from a molding resin except outer leads. SOLUTION: When a lead frame is resin sealed, an inside of a package hanging lead is sealed in a resin, and a laminating positioning lead 4 is partly exposed. In the frame, the resin is formed, and resin burr occurs at an inside of a tie bar. When the burr occurs at the inside of the lead, a positioning accuracy at the time of laminating is deteriorated, and hence a structure in which no resin burr occurs at the inside of the lead 4 is formed. A laminating jig 11 is formed in a protrusion state to be mated to a recess shape of the lead 4. Since the lead 4 having a region of no burr and the jig 11 can be positioned when laminated, accurate positioning can be executed.
