When a core lens is introduced into a cavity, resin is injected into the cavity, and a resin layer is formed around the core lens, the core lens is centered by sandwiching the core lens between first and second bell clamp type holders and applying a load to the core lens, and the resin layer is molded by injecting the resin from the outer periphery of the core lens to the lens center of the core lens in the first and second bell clamp type holders.
