PROBLEM TO BE SOLVED: To provide an electro-optical conversion module capable of improving productivity and assembly properties and reducing manufacturing costs. SOLUTION: A lower substrate 10, an intermediate substrate 20, and an upper substrate 30 are laminated in order from the lower side. The lower substrate 10 includes a light reception/emission element 50 mounted on the upper surface thereof, conductor patterns 41, 42 and so forth for conducting the light reception/emission element 50 to the outside, and insertion through-holes 12 which are formed in the direction of the substrate thickness and through which positioning pins 60 are inserted. The intermediate substrate 20 includes an accommodation hole 21 accommodating the light reception/emission element 50, and insertion through-holes 22 which are formed in the thickness direction of the substrate and through which the positioning pins 60 are inserted. The upper substrate 30 includes a through-hole 31 which is formed in the thickness direction of the substrate and through which an optical fiber 70 is inserted and insertion through-holes 32 which are formed in the thickness direction of the substrate and through which the positioning pins 60 are inserted. The front end face 71 of the optical fiber 70 is disposed opposite to the light reception/emission element 50. COPYRIGHT: (C)2007,JPO&INPIT
