Abstract
A composite member excellent in corrosion resistance of a substrate and excellent in heat radiation property is provided. A composite member includes a substrate composed of a composite material containing magnesium or a magnesium alloy and SiC and a coating layer provided on a surface of the substrate. The coating layer includes an outermost layer provided as an outermost surface and an intermediate layer provided directly under the outermost layer. The outermost layer contains nickel and phosphorus. The intermediate layer is mainly composed of copper. The intermediate layer has a thickness not smaller than 30 μm.
