Summary:PROBLEM TO BE SOLVED: To provide a method for producing a molded resin component which can improve the dimensional accuracy of a necessary part and an yield of the component. SOLUTION: In the method for producing the molded resin component which has a pair of arms 11 facing each other and is required for accuracy in a space H between opposite parts of the arms 11, a gate 21 for molding is arranged at the end of each of a pair of the arms 11, the molded resin component 10 is injection-molded while a resin-remaining part of a part including the two gates 21 and a runner 22 connecting the two gates 21 to each other is attached integrally as a bridge member 20 connecting ends of a pair of the arms, an injection-molded article is annealed with the bridge member 20 attached, the bridge member 20 is cut at positions of the gates 21 after annealing, and a product is obtained.
