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 10):
A method for manufacturing a bonded body including a ceramic member formed of ceramics and a Cu member formed of Cu or a Cu alloy, the method comprising:\n a CuTi diffusing step of diffusing Cu and Ti by performing heating in a state where the Cu member and the Ti material are laminated so as to form a first intermetallic compound layer which is positioned between the Cu member and the Ti material and contains Cu and Ti; a laminating step of laminating the ceramic member and the Ti material and the Cu member, between which the first intermetallic compound layer is formed, through a Cu\u2014P\u2014Sn-based brazing material; and a heat treatment step of performing heating at a temperature equal to or higher than a melting start temperature of the Cu\u2014P\u2014Sn-based brazing material so as to form a Cu\u2014Sn layer in which Sn forms a solid solution in Cu and a second intermetallic compound layer which is positioned between the first intermetallic compound layer and the Cu\u2014Sn layer and contains P and Ti.
