PROBLEM TO BE SOLVED: To reduce distortion of an image in the vicinity of a center of spiral in a fiber-optic scanning endoscope which performs spiral type scanning.;SOLUTION: The fiber-optic scanning endoscope has a light supply fiber 53, a fiber drive 54, and a top optical unit 60. The light supply fiber 53 emits light from an emitting end. The fiber drive 54 bends the light supply fiber 53 from a first line L1. The top optical unit 60 has first and second mirrors 61 and 62. The first mirror 61 reflects light emitted by the light supply fiber 53 to the second mirror 62. The second mirror 62 reflects light reflected by the first mirror 61 to a direction including the first direction as a positive vector and going toward a point on the first line L1.;COPYRIGHT: (C)2010,JPO&INPIT
