To enhance uniformity of heat history between die molded products when heating a molding material in a plurality of cavities in a die to manufacture a plurality of die molded products.

A manufacturing apparatus 1 includes the die 10 formed with the plurality of cavities 13 inside, and molds the molding material in the plurality of cavities 13 of one die 10 and heats the molding material to manufacture the plurality of die molded products. The manufacturing apparatus 1 includes a die heating means 30 heating the whole die 10, and a plurality of cavity heating means 50 heating the plurality of cavities 13 of the die 10 individually. While heating the whole die 10 by the die heating means 30, the respective cavities 13 of the die 10 are heated by the cavity heating means 30 respectively. The plurality of cavities 13 are thus heated individually to regulate temperature.
