Abstract
Abstract An optical module comprises at least one optical sub-module having at least one optical connector for receiving an end portion of an optical fiber at an end portion of the optical connector so as to optically couple the end portion of the optical fiber with an optical operation element, and a molded resin member for holding the optical connector except for the end portion of the optical connector; and at least one receptacle for enveloping the end portion of the optical connector to integrally hold the optical sub-module, the receptacle having an opening portion for fitting with an optical plug holding the end portion of the optical fiber which is to be received by the optical connector. The receptacle is resin-molded by using a mold die including a core for forming an opening portion of the optical module, the core having at least one hold portion for holding a portion of the optical sub-module.
