1. A urethane foam-molded article comprising:
a base material made of polyurethane foam; and
composite particles that are included and oriented in the base material,
wherein the composite particles have thermally conductive particles that are made of a non-magnetic material and have a thermal conductivity of 200 W/m·K or higher and magnetic particles attached to surfaces of the thermally conductive particles with a binder and are surface-treated with one or more surfactants selected from a carboxylic acid surfactant and a succinic acid surfactant;
wherein the thermally conductive particles have at least one of graphite particles and expanded graphite particles, and the magnetic particles have at least one of iron particles and stainless steel particles.
