容易である等の効果がある。As described above, the present invention is a resin molding method for a driven magnet in a magnetic pump, and in the first step, the outside of one end of a part of the cover that covers the outer periphery and one axial end of the driven magnet is exposed to a surface mirror of an injection molding mold. In a second step, the impeller body is formed by molding the part of the driven magnet that was not covered with the synthetic resin in the first step and the impeller body that covers the outside of the one end. Since the synthetic resin is injection-molded so as to have the same shape, the surface mirror on the outer side of the one end can improve the bonding force between the cover and the impeller main body. In addition, the bonding force can be improved simply by using the surface mirror, and there is no need to provide bottles or bottle holes in the injection mold, which reduces the occurrence of injection molding defects and makes it easier to manufacture and clean the injection mold. It has the advantage of being extremely easy.
