<P>PROBLEM TO BE SOLVED: To provide an optical fiber socket, that not only simplifies optical axis alignment between an optical fiber and a photoelectric conversion element, but also improves precision of the optical axis alignment, thus improving reliability and extending lifetime of the photoelectric conversion element. <P>SOLUTION: A socket 1 comprises: a circuit board 31 and a sleeve block receptacle member 32 that are molded at the same time; and a sleeve block 4. By fitting a fitting projection 42 of the sleeve block 4 to a fitting hole 32b of the sleeve block receptacle member 32, a photoelectric conversion element 2 is hollow-sealed, and an optical axis of an optical fiber 10 and an optical axis of the photoelectric conversion element 2 are aligned. In a gap between the sleeve block 4 and a frame 32c of the sleeve block receptacle member 32 surrounding the sleeve block 4, a sealing member 6 is inserted. Accordingly, an optical axis alignment is performed only by fitting and insertion. Further, since maximum molding precision obtained with a molding technique has a dimensional error of not more than 1 μm, precision of the optical axis alignment is improved by using the same degree of precision for dimensions and positions of the fitting projection 42 and the fitting hole 32b. Further, airtightness of a sealing space is increased. <P>COPYRIGHT: (C)2013,JPO&INPIT |
