Abstract
An optical device and a method for manufacturing the optical device. An optical device having a molded-package structure includes: a lead frame having a ferrule-mounting portion; a ferrule mounted on the ferrule-mounting portion; and a molding resin that encapsulates the lead frame and the ferrule, molding, except that an end of the ferrule protrudes through and outside of the surface of the molding resin. The first groove parallel to a longitudinal axis of the ferrule is located on the ferrule-mounting portion and the ferrule is placed on the first groove. Thus, the ferrule is hardly ever detached from a ferrule-mounting portion, an optical fiber is hardly ever damaged, and an optical coupling is hardly ever obstructed.
