A method of manufacturing a vehicle-body structural component includes: forming a cylindrical molded body made of a fiber-reinforced resin by molding a continuous fiber impregnated with a thermoplastic resin into a cylindrical shape and curing the thermoplastic resin; disposing a component in a space on an inner peripheral side of the molded body; and heating at least a portion of the molded body to melt the thermoplastic resin while maintaining continuity of a fiber in an axial direction of the molded body and continuity of a fiber in a circumferential direction around an axis of the molded body, deforming the at least a portion of the melted molded body from an outer peripheral side toward the inner peripheral side of the molded body to form projections projecting toward the inner peripheral side so as to come into contact with the component, and then curing the thermoplastic resin again.
