BONDED BODY AND INSULATED CIRCUIT BOARD
A bonded body (10) is formed by bonding a ceramic member (11) formed of an Al-based ceramic and a copper member (12) formed of copper or a copper alloy, in which, in a bonding layer (30) formed between the ceramic member (11) and the copper member (12), a crystalline active metal compound layer (31) formed of a compound including an active metal is formed on a ceramic member (11) side, and, the Al concentration is 0.15 at% or less in a thickness range of 0.5 µm to 3 µm from an interface of the active metal compound layer (31) on a copper member (12) side toward the copper member (12).
