PROBLEM TO BE SOLVED: To provide an irradiating device capable of adjusting simply and effectively the irradiation range of light to irradiate on an object, while effectively evading adoption of a lens. SOLUTION: The irradiating device is equipped with an optical fiber part 12 which emits light entered from a base end from a top end, an emitting side outer tube 11 and an incident side outer tube 13 which respectively have an emitting side reflection surface 112 and an incident side reflection surface 132 capable of reflecting the light at inner face and are installed on the optical fiber part, and a relative movement part S which can relatively move a part of the emitting side outer tube 11 and the incident side outer tube 13 to a position pushed out from the base end or the top end of the optical fiber part 12.
