Abstract:
A bonded body of the present invention includes a ceramic member formed of ceramics and a Cu member formed of Cu or a Cu alloy. In a bonded interface between the ceramic member and the Cu member, a Cu—Sn layer which is positioned on the ceramic member side and in which Sn forms a solid solution in Cu, a first intermetallic compound layer which is positioned on the Cu member side and contains Cu and Ti, and a second intermetallic compound layer which is positioned between the first intermetallic compound layer and the Cu—Sn layer and contains P and Ti are formed.

Claim (Index 14):
A method for manufacturing a power module substrate in which a circuit layer is provided on one surface of a ceramic substrate and a metal layer formed of Cu or a Cu alloy is provided on the other surface of the ceramic substrate, the method comprising:\n bonding the ceramic substrate and the metal layer to each other by the method for manufacturing a bonded body according to  claim 8 .
