PROBLEM TO BE SOLVED: To provide a method for manufacturing a molded product which has a uniform quality and is free from air bubbles or the like, in the method for injection-molding a phenol resin. SOLUTION: When a resin molding material which is composed of an uncured phenol resin and a phenol resin cured to the stage C and has a heat fluidity of 110 to 140 mm measured by a disc cure method, is injection-molded, the mold is heated at 150 to 170°. Preferably, the heat fluidity of the uncured phenol resin measured by the disc cure method is set at 130 to 180 mm, or the average particle diameter of the phenol resin cured to the stage C is set at 100μm or less.
