Patent ID: 8562195

Claim:
A light-emitting module, comprising: (i) a light-emitting device having a light-emitting end surface from which light is emitted; (ii) an optical fiber which is a multi-mode fiber, the optical fiber including: a core part extending along a light-guide direction in which light is guided; and a cladding part extending along the light-guide direction and covering the core part, the cladding part having a refractive index lower than that of the core part, the optical fiber having a covered fiber section and a bare fiber section, the covered fiber section including a covering part extending along the light-guide direction and covering the cladding part, the bare fiber section having a light-receiving end into which the light enters, the bare fiber section being not covered with the covering part; and (iii) a housing in which the light-emitting device is provided, the housing including a fixing part for fixing a portion of the bare fiber section such that the light-emitting end surface of the light-emitting device and the light-receiving end of the bare fiber section face each other, the fixing part fixing the portion of the bare fiber section by a resin material having a refractive index lower than that of the cladding part in the bare fiber section, wherein: the fixing part includes an optical fiber penetration pipe having a penetration hole through which the light-receiving end of the bare fiber section is penetrated; and the penetration hole of the optical fiber penetration pipe includes, inside thereof, a resin sealing part for sealing with the resin material an area surrounding the portion of the bare fiber section in a state where the bare fiber section is penetrated through the penetration hole.
