PROBLEM TO BE SOLVED: To provide a module that is not only high in coupling efficiency and reliability but also easy to produce with a simple structure, by forming a ferrule and/or a sleeve for leading out an optical fiber integrally with a package from ceramics. SOLUTION: Inside the package to be airtightly sealed by a main body 10 of package and a lid member 17, a silicon substrate 20 having a V groove 21 is arranged. Then, an optical fiber 31 photocoupled with a photoelectric transducer 24 on the silicon substrate 20 is led outside and a lead pin 16 forming an external lead and the photoelectric transducer 24 are electrically connected. In this case, the main body 10 of package is composed of ceramics and box- shaped while opening its upper part, a ferrule 11 having a through hole 12 is integrally formed on its side face, a step part 14 is provided on its inner peripheral surface, and the lead pin 16 is inserted and fixed into a through hole 15 formed at the step part 14. The lead pin 16 is fixed completely through the inside and outside, and an outside flange part forms the external lead. |
