摘要

This substrate for a power module is provided with an insulation layer (11), a circuit layer (12) formed on the first surface of the insulation layer, and a metal layer (13) formed on the second surface of the insulation layer. A first base layer (20) is layered on the surface of the metal layer on the opposite side to the surface at which the insulation layer is installed. The first base layer has a first glass layer formed on the interface with the metal layer and a first Ag layer layered on the first glass layer.
