Abstract
Bondability and heat conductivity of a bonded body in which some of metal, ceramic, or semiconductor are bonded to each other are improved. In the bonded body in which a first member and a second member each comprise one of metal, ceramic, or semiconductor are bonded to each other, the second member is bonded to the first member by way of an adhesive member disposed to the surface of the first member, and the adhesive member contains a VO-containing glass and metal particles. In a semiconductor module having a base metal, a ceramic substrate, a metal wiring, and a semiconductor chip, the ceramic substrate is bonded to the base metal by way of a first adhesive member disposed to the surface of the base metal, the metal wiring is bonded to the ceramic substrate by way of a second adhesive member disposed to the surface of the ceramic substrate, the semiconductor chip is bonded to the metal wiring by way of a third adhesive member disposed to the surface of the metal wiring, and the first adhesive member, the second adhesive member, and the third adhesive member each comprise a VO-containing glass and metal particles.
