The first optical element has a first light incident surface which faces the first laser light emitter, a first reflection surface that reflects the first light emitted from the first light incident surface and deflects the optical path of the first light, and a first light exiting surface which faces the wavelength converter and via which the first light reflected off the first reflection surface exits. The first light incident surface, the first reflection surface, and the first light exiting surface intersect with each other.
