A light receiving/emitting element module is provided by the invention, in which a light receiving/emitting element of a face light receiving/emitting type can be easily aligned and fixed with precision, and whose cost is low. At element loading surface (10) side of element loading substrate (1) onto which face light emitting laser array (8) is loaded, substrate side fitting parts (5) are provided, and ferrule side fitting parts (4) are provided in ferrule (2). Element loading surface (10) of element loading substrate (1) and connection end face (9) of ferrule (2) are disposed opposite each other, common micro balls (6) are fitted in the substrate side fitting parts (5) and ferrule side fitting parts (4) opposite each other to fix ferrule (2) and element loading substrate (1). Thereby, the optical axis of face light emitting laser array (8) and the optical axes of optical fibers (11) inserted and fixed in optical fiber insertion holes (3) in ferrule (2) are precisely aligned, and face light emitting laser array (8) and optical fibers (11) are optically connected to each other.
