PROBLEM TO BE SOLVED: To provide a high-output optical fiber module which converts leakage light into heat so as to release it outside.SOLUTION: An optical fiber module 1 includes: a package housing 10; a laser device 20 arranged in a package internal space S inside the package housing 10; and an optical fiber 30 propagating a laser beam from the laser device 20 outside. The optical fiber 30 includes a protruding end part which protrudes from an inner wall surface of the package housing 10 toward the package internal space S. A light scattering body 40A extending from the inner wall surface of the package housing 10 toward the package internal space S covers a periphery of the protruding end part of the optical fiber over a length L. |
