摘要： A composite member includes: a substrate formed of a composite material containing a plurality of diamond grains and a metal phase; and a coating layer made of metal. The surface of the substrate includes a surface of the metal phase, and a protrusion formed of a part of at least one diamond grain of the diamond grains and protruding from the surface of the metal phase. In a plan view, the coating layer includes a metal coating portion, and a grain coating portion. A ratio of a thickness of the grain coating portion to a thickness of the metal coating portion is equal to or less than 0.80. The coating layer has a surface roughness as an arithmetic mean roughness Ra of less than 2.0 μm.
