INSULATED CIRCUIT BOARD
In an insulating circuit substrate (10), aluminum sheets (12, 13) formed of aluminum or an aluminum alloy are laminated and bonded to a surface of a ceramic substrate (11) and, in the aluminum sheets (12, 13), Cu is solid-solubilized at a bonding interface with the ceramic substrate (11) and a ratio B/A between a Cu concentration A mass% at the bonding interface and a Cu concentration B mass% at a position of 100 µm in a thickness direction from the bonding interface to the aluminum sheets (12, 13) side is 0.30 or more and 0.85 or less.
