Abstract
A resin lens includes an optical functional section that has an optical function, and a flange section that is formed around the optical functional section. A reference face is used as reference during positioning and fixing, and is formed on one face of the flange section. The face on which the reference face is formed is molded by an insert that mainly forms the optical functional section and a holder that mainly forms the flange section, during molding. The reference face of the flange section and an optical functional face that is the face of the optical functional section facing the reference face are molded by the insert, and a face of the flange section that is closer to the outer periphery than the reference face of the flange section is molded by the holder.
