PROBLEM TO BE SOLVED: To reduce a cost required during replacement by reducing replacement components by reusing parts in which defects are not generated.SOLUTION: A fiber scope includes: a fiber 4 mounted with a lens 5 to one end part a sleeve 9 mounted to the other end part of the fiber 4 and covering the outer periphery of the fiber 4 an image converting part for photoelectrically converting an optical image taken from a lens 5 and passing through the fiber 4 a connecting component 7 formed with a through-hole 7a through which the fiber 4 penetrates and detachably connecting the sleeve 9 at a predetermined position of the image converting part while the fiber 4 penetrates through the through-hole 7a and an elastic body 8 provided between the sleeve 9 and the connecting component 7 and urging the sleeve 9 in the direction of the image converting part when mounting the sleeve 9 at the predetermined position. A diameter R of the through-hole 7a is larger than an outer diameter r of the lens 5 and smaller than an outer diameter Rof the elastic body 8.
