1. A scanning endoscope comprising:
an optical fiber configured to guide illuminating light for illuminating a subject and emit the illuminating light from a distal end; an actuator for swinging a distal end of the optical fiber, the actuator being provided lateral to the optical fiber; a first tubular member having a hollow tubular shape, the first tubular member including a space that encloses a distal end of the optical fiber and the actuator; a holding portion provided on a proximal end side of the optical fiber relative to the actuator in an inner space of the first tubular member, the holding portion holding the optical fiber so that a distal end of the optical fiber is swung by the actuator; a second tubular member having a hollow tubular shape, the second tubular member including a space that encloses the first tubular member; a fixing portion that is disposed in an area perpendicular to a longitudinal direction of the optical fiber, the area being aligned with a position where the holding portion is disposed, and is configured to fix the first tubular member to the second tubular member; and a distal end fixing portion that is provided at a distal end of the first tubular member, and is configured to fix the first tubular member to the second tubular member. |
