Abstract:
1. A semiconductor power module comprising: a metallic base; an insulating substrate fixedly laminated on the metallic base, the insulating substrate including a plate-like insulating body and a surface conductive layer fixedly laminated on a surface of the plate-like insulating body via a surface side fixing member; a power semiconductor element mounted on the insulating substrate; and an electrode terminal plate fixed to the insulating substrate via a joint portion, wherein the surface side fixing member includes a first fixing portion for fixing one part of the surface conductive layer located underneath the joint portion of the electrode terminal, the first fixing portion formed of a first material including a metal, and a second fixing portion for fixing the other part of the surface conductive layer which is not located underneath the joint portion, and wherein a fixing strength exhibited by the first fixing portion is smaller than that exhibited by the second fixing portion.
