Abstract: There is provided a semiconductor module and a method for manufacturing the same which make it possible to joint the electrode of the bare-chip transistor and the wiring pattern on the substrate by solder mounting operation, in the same process of solder mounting operation for mounting the bare-chip transistor or other surface mounting devices on the wiring patterns on the substrate. A semiconductor module includes: a plurality of wiring patterns formed on an insulating layer; a bare-chip transistor mounted on one wiring pattern out of the plurality of wiring patterns via a solder; and a copper connector constituted of a copper plate for jointing an electrode formed on a top surface of the bare-chip transistor and another wiring pattern out of the plurality of wiring patterns via a solder.
