Abstract

PURPOSE:To bend a lead precisely and easily by forming a flexible section facilitating bending to the base section of the lead, using a resin sealing section as a reference after resin sealing and bending the lead at the flexible section. CONSTITUTION:A connecting section 6, etc., integrally connecting leads 20 are cut and removed while flexible sections consisting of notches 22 are formed at positions at equal distances (d) from the center 12 of a resin sealing section 5, using the resin sealing section 5 as a reference in the base sections of the leads 20 extending to the outside of the resin sealing section 5. Each lead 20 is bent by the flexible sections composed of the notches 22. Notch 22 forming sections have rigidity lower than other sections of the leads 20 and are easy to be bent, thus bending the leads 20 without peeling the resins of boundary sections with the resin sealing section 5 by stress at the time of the bending of the leads 20.
