Abstract
A light-emitting module including a light-emitting device, a multi-mode optical fiber, and a housing accommodating the light-emitting device is disclosed. The optical fiber includes a core and first cladding, and has a covered fiber section including a second cladding and a bare fiber section which has a lens for receiving laser light emitted by a light-emitting end surface of the light-emitting device and is not covered with the second cladding. The housing includes an optical fiber penetration pipe for fixing a portion of the bare fiber section so that the light-emitting end surface and the lens face each other. In the optical fiber penetration pipe, the portion of the bare fiber section is fixed by a resin having a refractive index lower than that of the first cladding.
