    Abstract: A composite material contains a metallic phase, a non-metallic phase and a specific element. At least 90 mass % of the metallic phase is composed of at least one selected from the group consisting of Ag and Cu. The non-metallic phase includes a coated core material. The coated core material includes a core material and a carbide layer that covers at least a part of a surface of the core material. The core material contains at least one carbon-containing material selected from the group consisting of diamond, graphite, carbon fibers, and silicon carbide. The carbide layer contains a carbide of at least one metal element selected from the group consisting of Ti, Cr, Ta, and V. The specific element is at least one selected from the group consisting of Y and Mg. A total content of the specific element is 0.0004 mass % to 1.3 mass %.
