Abstract
A metal mold is prepared, which has a gate, a cavity in which a virtual curve is formed, which forms at least a welding target part of a laser beam transmitting member along the virtual curve, and in which a filling terminal wall is formed along a curve parallel to the virtual curve, and a throttle part for reducing the flow of a resin flowing from the gate toward the cavity, which is connected to the cavity, and whose connection boundary is formed along a curve parallel to the virtual curve. Then, a resin is injected into the gate and a crystalline laser beam transmitting member is molded out of the injected resin using the metal mold.
