PROBLEM TO BE SOLVED: To provide a receptacle which minimizes an increase in coupling loss when an external force is exerted to a ferrule inserted into the receptacle and an increase of an attenuation rate of reflection and an optical semiconductor packaging module using the same. SOLUTION: The receptacle is equipped with a precision sleeve 11 holding a built-in stub ferrule 14 which is fixed with an optical fiber 15 to be coupled via space light to an optical semiconductor element at its central part and an insertion ferrule 16 which is inserted from outside and is made to abut on the ferrule 14 as a guide. The precision sleeve 11 is a sleeve of a uniform cylindrical shape which does not have a slit on its side face. COPYRIGHT: (C)2005,JPO&NCIPI
