<p>PROBLEM TO BE SOLVED: To provide a small sized optical module having excellent performance wherein not only deterioration of light quantity and breaking of an optical fiber are prevented to the utmost but also the optical fiber is reliably and optically connected to an optical device and productivity of the optical module is improved. SOLUTION: In the optical module M1 which is composed by positioning on a base 2 an optical part mounting board 1 having a groove 1a for an optical waveguide body on the main surface of which the optical waveguide body 7 is disposed and an optical semiconductor element mounting part which is positioned to the groove 1a for the optical waveguide body, one end part of the optical part mounting substrate 1 is formed so that the direction of the optical axis of the optical waveguide body 7 is tapered, and a guide part 9 for positioning and supporting the side surface of the tapered part of the optical part mounting substrate 1 by abutting the side surface on the base 2 is provided.</p> |
