摘要： Disclosed is an invention that aims to accurately position a lens barrel and an optical lens and form a plastic lens easily with a high-precision forming mold. A plastic lens is formed by filling resin into a cavity surrounded by a fixed mold, a movable mold, and inserts, which are removably incorporated into respective molds. A lens portion and conical surfaces of the plastic lens are formed with the inserts. This provides enhanced forming accuracy by making the conical surfaces and lens portion concentric with each other. When the plastic lens is to be incorporated into the lens barrel, the conical surface of the plastic lens is allowed to be in line contact with the vertical inner circumferential surface of the lens barrel to make the plastic lens concentric with the lens barrel for the purpose of accurate positioning.
