Thereby easily improving the heat transfer characteristic of the rubber article mold having the rubber molded part formed by sintering the metal powder. A rubber article mold (1) has a rubber molded part (10) which contacts a rubber article at a contact part (11) to mold a rubber article and a holding part (20) which holds the rubber molded part (10) . The metal powder is sintered to form a rubber molded part (10). A part or the whole of a portion excluding the contact portion (11) of the rubber molded portion (10) is cast-wrapped by the holding portion (20) during casting of the holding portion (20), and the holding portion (20) and the holding portion (20) (14) of the rubber molded part (10) to be cast-in by the casting part (14).
