METHOD FOR MANUFACTURING SUBSTRATE FOR POWER MODULE WITH HEAT SINK
In an aluminum material that constitutes a bonding surface of a metal layer, and an aluminum material that constitutes a bonding surface of a heat sink, any one aluminum material is set to a high-purity aluminum material with high aluminum purity, and the other aluminum material is set to a low-purity aluminum material with low aluminum purity. The difference in a concentration of a contained element other than Al between the high-purity aluminum material and the low-purity aluminum material is set to 1 at% or greater, and the metal layer and the heat sink are subjected to solid-phase diffusion bonding.
