An endoscope (2) is provided with: an insertion section (11) to be inserted into a living organism; an illumination fiber (14) disposed at the distal end of the insertion section (11) and applying illumination light to the living organism; a detection fiber (16) for detecting light returning from the living organism; an actuator (15) for causing the free end of the illumination fiber (14) to pivot; and a ferrule (41) having a through-hole which corresponds to the diameter of the illumination fiber (14) and disposed between the illumination fiber (14) and the actuator (15). The actuator (15) is provided with: an actuator (15a) disposed on a first side surface (42a) of the ferrule (41); and an actuator (15b) disposed on a second side surface (42b) of the ferrule (41), the second side surface (42b) being a surface different from a surface point-symmetric to the first side surface (42a) with respect to the axial direction of the illumination fiber (14).
