PROBLEM TO BE SOLVED: To provide an optical part mounting method and an optical part mounting device by which plural optical parts are accurately mounted, with respect to an optical part mounting method and an optical part mounting device, for integrally mounting a light-emitting element and an optical element. SOLUTION: The quantity of light emitted through the optical components from a light source is detected, and also the returning light which is the emitted light is detected. Then, the optical components are positioned according to relation between the quantity of the light emitted and the quantity of the returning light, such as a value obtained by dividing the returning light by the quantity of the emitted light. |
