An optical module having an optical element mounting substrate (2) and a package (4) with high precision is provided. A positioning groove (9) is formed in the mounting surface of the mounting substrate (2) on which an optical element (1) is mounted, and a package side positioning groove (5) is formed in the package (4) on which the mounting substrate is arranged. The optical element mounting substrate and the package are overlapped with each other with the substrate side positioning groove portion and the package side positioning groove portion facing each other. An optical fiber (3) that is a positioning member is inserted between the positioning groove portions. Thus, the optical element mounting substrate and the package are aligned. <IMAGE> |
