PROBLEM TO BE SOLVED: To provide a resin molding method capable of selectively heating the thermoplastic resin in a cavity with respect to a mold made of a rubber to obtain a good resin molded product, and a resin molding apparatus. SOLUTION: The resin molding apparatus 1 has the mold 2 made of the rubber having a cavity 21 formed thereto, a vacuum means 61 for bringing the inside of the cavity 21 to a vacuum state and an electromagnetic wave generating means 4 for emitting an electromagnetic wave (near infrared rays) with a wavelength of 0.78-2μm is used and constituted so as to perform a vacuum process for bringing the inside of the cavity 21 of the mold 2 made of the rubber to a vacuum state, a filling process for filling the cavity 21 of the vacuum state with the thermoplastic resin 3 of a molten state and a cooling process for cooling the thermoplastic resin 3 in the cavity 21 to obtain the resin molded product. In the filling process, the thermoplastic resin 3 is irradiated with near infrared rays through the mold 2 to selectively heat the thermoplastic resin 3 with respect to the mold 2.
