PROBLEM TO BE SOLVED: To provide an inspection system capable of effectively illuminating the inner surface of a pipe, according to the inner diameter of the pipe, with a simple configuration.
SOLUTION: The inspection system 1 includes: an insertion portion 2 which is inserted into the pipe an objective optical system 3 which has a predetermined optical axis C1 and can observe the range of a view angle an illumination unit for a small diameter 5 for a pipe having a first inner diameter and an illumination unit for a large diameter 6 for a pipe P2 having a second inner diameter larger than the first inner diameter. The light emitting portion 40a of the illumination unit for a large diameter is arranged over a range in an optical axis direction wider than the light emitting portion 46a of the illumination unit for a small diameter, when the respective illumination units attached to the insertion portion 2 are viewed from a direction orthogonal to an optical axis.
