PURPOSE:To obtain a highly reliable power module of low cost wherein short- circuit failure is not caused by contact with other main electrode, by constituting a form capable of connection with internal signal terminals by using a sealed plate type integrated terminal. CONSTITUTION:A sealed plate type integrated terminal 19 is constituted in the manner in which signal tab terminals 21B-24B and lead line parts 21C-24C are unified in a body of plate type and sealed with resin 19A. The lead line parts 21C-24C of the sealed plate type integrated terminal 19 are inserted in two-branch parts of internal signal electrode terminals 9, 10, 11, 20; the two- branch parts are caulked, and the tab terminal parts 21B-24B are fixed and soldered. A process wherein the lead lines 21-24 are soldered to the tab terminal 21A-24A in a conventional process can be omitted. By inserting the sealed plate type integrated terminal 19 in a resin case 17, the insertion positioning for the hole part of a lid 18 can be accurately performed, so that, when the lid is fixed, the tab terminals 21B-24B can be smoothly inserted into the hole part of the lid. Thereby, short-circuit failure wherein the terminal parts are brought into contact with other main electrodes as in the case of lead wires is not caused. |
