An endoscope includes: a first fiber provided with a first flat surface from which illuminating light is emitted; a pipe including a through hole to which a distal end portion of the first fiber is fixed and including a first surface that can be a flat surface identical to the first flat surface and a second surface which is a flat surface orthogonal to a central axis of the through hole; and a distal end component in which a stopper hole in which an end portion on the distal end side of the pipe is disposed is formed, the stopper hole including an abutting surface on which at least part of the second surface of the pipe abuts, on a bottom side, a concave portion which constitutes for obtaining a predetermined light distribution and is located closer to the front end side than the abutting surface.
