Abstract
An optical module includes a light-forming part and a protective member. The light-forming part includes a base member, a semiconductor light-emitting device, a lens, and a light-receiving device mounted on the base member and disposed, in the emission direction of the semiconductor light-emitting device, between the semiconductor light-emitting device and the lens. The light-receiving surface of the light-receiving device inclines toward the emission portion of the semiconductor light-emitting device such that an inclination angle θ is more than 0° and 90° or less, the inclination angle θ being an angle formed between the optical axis of the semiconductor light-emitting device and a plane including the light-receiving surface of the light-receiving device.
