PURPOSE:To improve the connection strength between a lead and a gold wire by exposing the core material of a tape partially without exposing a binder all over the surface of the adhesive tape. CONSTITUTION:The inner lead of a lead 1 extended from an outer frame 6 is bonded to a heat radiation plate 2 through an insulating two-sided thermosetting adhesive tape 3. The junction part 7 with the inner lead section and the junction part 8 with the heat radiation plate 2 are constituted such that the adhesive face 32 and the core face 34 are partially exposed. Since the exposure of the adhesive face is small, the generation of the organic gas is suppressed, and the connection strength of the wire connection on a lead can be improved without causing the shortage of connection strength resulting from an adhesive adhering to the wire connection face on an inner lead. |
