Abstract: This optical scanning actuator can improve yield and assembly efficiency. An optical scanning actuator (10) includes a piezoelectric element (14) that is joined to a displaceably supported emission end (11a) of an optical fiber (11) and displaces the emission end (11a) in a direction perpendicular to an optical axis direction of the optical fiber (11) by expanding and contracting in the optical axis direction. The piezoelectric element (14) includes an identifier (16) for identifying a polarization direction, the identifier (16) being formed physically.

Abstract: A scanning endoscope includes an optical fiber that illuminates a living body, a holding member that holds the optical fiber, in which the optical fiber is provided so as to extend from a distal end face by a predetermined length, and a concave portion that communicates with the insertion hole is formed on the distal end face, a drive portion that is provided in the holding member, and causes a free end of the optical fiber that extends from the distal end face of the holding member to scan, and an adhesive portion that is coated on or filled in the concave portion to firmly fix the optical fiber and the holding member to each other, and has a plane which is flush with the distal end face of the holding member formed thereon.

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.
