Abstract
This optical fiber scanner has an elongated optical fiber, a vibration transmission member which has a column-like shape and has a penetrating hole through which the optical fiber penetrates, and a piezoelectric element provided on an outer surface of the vibration transmission member, wherein the penetrating hole is a fitted hole which is formed from a proximal end of the vibration transmission member to a middle of the vibration transmission member and the optical fiber is fitted, and the penetrating hole is an accommodation hole which is formed from the middle to a distal end of the vibration transmission member, which has a large inner diameter than an outer diameter of the optical fiber, and which accommodates a distal end portion of the optical fiber with a gap between the optical fiber and the accommodation hole.
