Abstract
The present invention provides an optical module, in which aligning adjustment is much easier than conventional module while a high optical coupling efficiency between an optical fiber and a semiconductor device is maintained. The module comprises a structure for effectively suppressing the decrease in optical coupling efficiency caused by changes in ambient temperature. The optical module comprises an optical reflecting member having a reflecting surface with a concave surface form for optically coupling the optical fiber and the semiconductor device to each other, and a deterioration-suppressing structure in which the change in shape of the reflecting member caused by changes in ambient temperature effectively suppresses the deterioration in optical coupling state between the optical fiber and semiconductor device due to changes in temperature or the like.
