Abstract
A urethane foam molded body includes a base material composed of polyurethane foam, a composite particle oriented and contained in the base material, and a first insulating inorganic particle dispersed in the base material. The composite particle includes a thermally conductive particle, and a magnetic particle adhered to a surface of the thermally conductive particle by a binder. The thermally conductive particle includes an expanded graphite particle, and an amount of an alkali metal ion contained in the expanded graphite particle is 500 ppm or higher and 2,000 ppm or lower.
