PROBLEM TO BE SOLVED: To provide a resin molding apparatus for obtaining a cured article of a resin for molding which has little bubbles inside, wherein the resin for molding stored in a pot is sandwiched between an injection plunger and a pressure regulating plunger and pressurized and then pressure is applied with the injection plunger to supply the resin to a cavity via a runner. SOLUTION: Heat conductance from a pressure regulating plunger 18 is increased so as to decrease the viscosity of a resin A for molding, by forming, on the surface of the plunger 18 facing an injection plunger 17, a protrusion 182 which protrudes toward the side of the plunger 17, or a depression 184 which is depressed toward the side opposite to the plunger 17.
