Fiber-reinforced resin member and method for manufacturing fiber-reinforced resin member

A method for manufacturing a fiber-reinforced resin member in which a mounting hole into which a securing member is fixed is formed in a plate material reinforced by embedding a fiber in an interior of a thermosetting resin, the method comprising:

• a step of layering in an interior of a mold a plurality of prepregs having an opening that is larger than a mounting hole molding pin so as to fit onto the mounting hole molding pin to thus surround an outer periphery of the mounting hole molding pin with edges of the openings, the edges being in a nonuniform state;
• a step of fitting an insert member, formed into a tubular shape by impregnating a fiber with a thermosetting resin, between the opening and the mounting hole molding pin;
• and
• a step of hot pressing and curing the prepreg and the insert member by clamping and heating the mold so as to fill the openings, in a state in which the edges thereof are nonuniform, with the insert member, which has been compressed and spread in a radial direction within the mold.
