The purpose of the present invention is to prevent misalignment between a wiring pattern provided on a support member and a piezoelectric element in terms of position in the rotational direction. The present invention provides an optical fiber scanner (1) including an optical fiber (2) for guiding illumination light to be emitted from a tip thereof, vibrating parts (3, 4) for vibrating the tip of the optical fiber in a direction intersecting the longitudinal axis, and a support member (5) for supporting the vibrating parts, wherein the vibrating parts include a piezoelectric element (4) that vibrates when a voltage is applied thereto and an elastic member (3) that is formed into a tubular shape into which the optical fiber is passed through and transmits the vibrations of the piezoelectric element to the optical fiber, a fitting part (32) with a non-circular cross section being provided on at least a portion of the length, and the support member includes a recess into which the fitting part is inserted, a detent (32) that locks rotation of the fitting part about the longitudinal axis while the fitting part is inserted into the recess, and a wiring pattern (54) that is formed on an outer peripheral surface and connects to the piezoelectric element while the fitting part is inserted into the recess.Le but de la présente invention est d'empêcher un désalignement entre un motif de câblage disposé sur un élément de support et un élément piézoélectrique en termes de position dans le sens de rotation. La présente invention concerne un scanner à fibre optique (1) comprenant une fibre optique (2) pour guider une lumière d'éclairage à émettre depuis une pointe de celle-ci, des parties vibrantes (3, 4) pour faire vibrer la pointe de la fibre optique dans une direction croisant l'axe longitudinal, et un élément de support (5) pour supporter les parties vibrantes, les parties vibrantes comprenant un élément piézoélectrique (4) qui vibre lorsqu'une tension est appliquée à celui-c
