Bonded body and power module substrate
The bonded body of the present invention includes: a ceramic member made of ceramics; and a Cu member which is made of Cu or a Cu alloy and bonded to the ceramic member through a Cu—P—Sn-based brazing filler material and a Ti material, wherein a Cu—Sn layer, which is positioned close to the ceramic member and in which Sn forms a solid solution with Cu, and a Ti layer which is positioned between the Cu member and the Cu—Sn layer, are formed at a bonded interface between the ceramic member and the Cu member, a first intermetallic compound layer made of Cu and Ti is formed between the Cu member and the Ti layer, and a second intermetallic compound layer containing P is formed between the Cu—Sn layer and the Ti layer.
