PROBLEM TO BE SOLVED: To provide a fiber-reinforced resin gear including a tooth profile section advantageous in strength even when the tooth profile section is formed by a cutting process. SOLUTION: A fiber-reinforced resin gear 11 comprises a fiber-reinforced resin section 13 in which a tooth profile section 14 is formed in a periphery. Furthermore, the fiber-reinforced resin section 13 uses an annular three-dimensional structure braiding fibers, which is formed in lamination by spirally rolling a strip structure of braiding fibers, a 4 axes three dimensional cord structure, as a reinforcement.
