Abstract
In a fixing portion of an optical fiber-type wave-divider-multiplexer, an optical fiber glass portion is fixed to a fixing member by an adhesive. A groove reaching at least a core portion of the optical fiber is cut from the fixing member. This groove may be cut up to a position where the optical fiber is cut across. An optical filter is inserted into the cut groove, and is fixed by an adhesive or the like. As a result, the optical fiber can be provided with light passing characteristics corresponding to the characteristics of the optical filter.
