Ceramic-aluminum conjugate, power module substrate, and power module
The present invention provides a ceramic-aluminum bonded body in which Mg-containing oxide having a spinel crystal structure are dispersed in an aluminum member within a range of 2 μm in a thickness direction from a bonded interface with a ceramic member, a segregated portion in which Mg, Si, and O is segregated is formed in the aluminum member in the vicinity of the bonded interface with the ceramic member, mass ratios of Mg, Si, and O between the segregated portion and a position spaced by 10 μm from the bonded interface toward an aluminum member side are within predetermined ranges, and the amount of Mg at the position spaced by 10 μm from the bonded interface toward the aluminum member side is 0.8 mass % or less.
