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 the surfaces of the thermally conductive particles with a binder and are surface-treated with one or more surfactants selected from a carboxylic acid-type surfactant and a succinic acid-type surfactant.
