An aluminum copper clad material has excellent bonding strength and includes an aluminum layer and a copper layer that are bonded without a nickel layer interposed therebetween. The aluminum layer and the copper layer are diffusion-bonded via an AlCu intermetallic compound layer. The copper layer satisfies Dcs0.5Dcc, where Dcc represents the average crystal grain size of crystal grains in a central portion in the thickness direction of the copper layer, and Dcs represents the average crystal grain size of an interface adjacent portion C2 in the copper layer that is about 0.5 m apart from the interface between the copper layer and the intermetallic compound layer. The intermetallic compound layer has an average thickness of about 0.5 m to about 10 m.
