Abstract
A composite material has a plate shape and has a first surface and a second surface. The second surface is opposite to the first surface. The composite material includes a plurality of first layers and at least one second layer. The first layers and the second layer are alternately layered along a thickness direction of the composite material such that the first layers are located at the first surface and the second surface. Each of the first layers is a layer including copper. The second layer is a layer of a molybdenum powder compact impregnated with copper. A compressive residual stress of 50 MPa or less acts on each of the first layer located at the first surface and the first layer located at the second surface.
