Abstract: An endoscope has an insertion portion inserted through a living body, an illumination fiber arranged at a distal end of the insertion portion and irradiates the living body with illumination light, a detection fiber which detects return light from the living body, an actuator which swings a free end of the illumination fiber, and a ferrule which has a through-hole based on a diameter of the illumination fiber and is arranged between the illumination fiber and the actuator. The actuator has an actuator arranged at a first side face of the ferrule and an actuator arranged at a second side face of the ferrule that is different from a face point-symmetric to the first side face with respect to an axial direction of the illumination fiber.

Abstract: The force of a piezoelectric element is efficiently transferred to an optical fiber without attenuation, so that the vibration of the optical fiber becomes large. Provided is an optical fiber scanner including an optical fiber which has an elongated cylindrical shape in which illumination light emitted from a light source is guided and can emerge from a distal end thereof and whose distal end can be vibrated in a direction intersecting the longitudinal direction thereof; and at least one piezoelectric element which have a plate shape polarized in a thickness direction thereof and which are separately bonded to an outer circumferential surface of the optical fiber closer to a base side than to a distal end thereof.
