Abstract
A reinforcing fiber sheet and a first thermoplastic resin sheet are stacked into a cylindrical shape to form a sleeve portion, and a second thermoplastic resin sheet is stacked around an outer periphery of the sleeve portion to form a tooth formation portion. Thereafter, the sleeve portion and the tooth formation portion are heated and pressed, and teeth are then formed in an outer periphery of the tooth formation portion to form a tooth portion. A gear is manufactured by this process.
