摘要
A composite particle includes: a first particle composed of a soft magnetic metallic material; and second particles composed of a soft magnetic metallic material having a different composition from that of the first particle and adhered to the first particle so as to cover the first particle, wherein when the Vickers hardness of the first particle is represented by HV1 and the Vickers hardness of the second particle is represented by HV2, HV1 and HV2 satisfy the following relationships: 250HV11200, 100HV2250, and 100HV1HV2, and when the projected area circle equivalent diameter of the first particle is represented by d1 and the projected area circle equivalent diameter of the second particle is represented by d2, d1 and d2 satisfy the following relationships: 30 md1100 m and 2 md220 m.
