摘要:
A method of assembling a photoelectric conversion module is disclosed. The photoelectric conversion module includes a circuit board (112) on which are mounted a light emitting element (122), a light receiving element (123), and an optical element (113) optically connected to the light emitting element and the light receiving element. The light emitting element (122) is positioned on the circuit board (112) based on a positioning mark formed on the circuit board beforehand. The light receiving element (123) and the optical element are positioned based on a position of a light emission point of the light emitting element.
