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.
