摘要:
An endoscope 10 includes: a first fiber 61 of a light guide fiber 60 provided with a first flat surface 61 f at a distal end portion from which illuminating light is emitted, inclined at an angle of less than 90 degrees with respect to a longitudinal axis 61a; a pipe 70 including a through hole 71 to which a distal end portion 61p of the first fiber 61 is fixed and including a first surface 73a that can be a flat surface identical to the first flat surface 61f and a second surface 73b which is a flat surface orthogonal to a central axis 71a of the through hole 71 on a front end face 73; and a distal end component 30 in which a stopper hole 34 in which an end portion on the distal end side of the pipe 70 is disposed is formed, the stopper hole 34 including an abutting surface 38f2 on which at least part of the second surface 73b of the pipe 70 abuts, on a bottom side, the stopper hole 34 including a concave portion 37 which constitutes an irradiation lens system to obtain a predetermined light distribution and is located closer to the front end side than the abutting surface 38f2.
