Abstract

In a molded body manufacturing method, after a raw material is put into a cavity of a mold, at least a part of the mold is irradiated with electromagnetic waves, or at least part of the mold is placed in an alternating electric field, to mold a molded body. The mold has a heating body, which absorbs the electromagnetic waves to generate heat or is placed in the alternating electric field to generate heat, outside the cavity. In at least part of a space between the heating body and the cavity, a transmission amount suppressing body that suppresses the amount of transmission of the electromagnetic waves or the alternating electric field into the cavity is provided, or at least part of the cavity is composed of the transmission amount suppressing body. When the heating body generates heat, the heat is transmitted to the raw material to perform molding.
