PROBLEM TO BE SOLVED: To provide an endoscope apparatus in which an illumination fiber can be stably driven by reducing influence of change in temperature.SOLUTION: The endoscope has: a slender insertion part 11 to be inserted in a reagent; an illumination fiber 14 inserted from a proximal distal end side of the insertion part 11 through to a distal end side and irradiating the reagent with illumination light; an actuator 15 oscillating a free end of the illumination fiber 14; and a ferrule holding the illumination fiber 14 in the direction parallel to a longitudinal direction of the insertion part 11. The ferrule is provided with a through-hole between a proximal end surface and a distal end surface, the actuator 15 is arranged on a side surface of the ferrule while the illumination fiber 14 is inserted in the through-hole, and at least a surface of the ferrule is formed with a conductive material.SELECTED DRAWING: Figure 1 |
