Abstract:
1. A method of manufacturing a composite optical component in which a core lens is introduced into a cavity formed by closing a first die and a second die, resin is injected from a resin injection gate to the cavity, and a resin layer is formed around the core lens, the method comprising: sliding and centering the core lens in contact with a first bell clamp type holder and a second bell clamp type holder by sandwiching the core lens between the first bell clamp type holder and the second bell clamp type holder and applying a load to the core lens; and molding the resin layer by injecting the resin from an outer periphery of the core lens to a lens center of the core lens in the first and second bell clamp type holders after the core lens is centered, wherein a first tangent line on a surface of the core lens and a second tangent line on a surface of the core lens form an angle of 6 to 8 degrees, the first tangent line located on a contact point between the surface of the core lens and the first bell clamp type holder, the second tangent line located on a contact point between the surface of the core lens and the second bell clamp type holder.
