To provide a manufacturing method of a high-strength lower spring seat which is hard to be damaged when large load acts momentarily, and the lower spring seat manufactured by the manufacturing method.SOLUTION: A manufacturing method of a lower spring seat 320 is a method manufacturing a lower spring seat 320 included in a suspension device 1 of a vehicle. The lower spring which is circle-like viewed from top surface is manufactured by pouring molding resin to inside of a metallic mold for injection molding 500 of a disk gate method from the center, and spreading and molding the poured molding resin inside the metallic mold for injection molding 500 radially. The lower spring seat is manufactured by the manufacturing method.SELECTED DRAWING: Figure 4
