Abstract
The production method for an optical fiber connector includes the steps of: injecting and hardening a first resin (26) into a resin-injection portion (29) of a connector body (22), the first resin (26) being a light hardening resin or a heat hardening resin; forming a pre-lens by further injecting a second resin (27) on the hardened first resin (26), the second resin (27) being the light hardening resin or the heat hardening resin; and forming a lens by hardening the second resin (27). In this way, it is possible to provide a production method for an optical lens by which influences by volume shrinkage of a resin are decreased, a lens surface can be formed with high accuracy and the product can be made with high quality.
