PROBLEM TO BE SOLVED: To solve the problem that a conventional inspection system for inspecting the optical member in a laser torch used to make the specifying work of an abnormal place and member exchanging work complicated to require much time because a produced abnormal mode is obscure. SOLUTION: The inspection system of the laser torch for inspecting the optical members 13, 14 and 15 in the laser torch includes the inspection light source 16 installed between the laser beam source and optical members in the laser torch 1, an imaging means 2 for photographing the image formed by the inspection light C passed through the optical members in the laser torch from the outside and a computer device 3 for comparing the photographed image due to the imaging means with the reference image preliminarily stored in a memory means 3a to detect the presence of the abnormality of the optical members on the basis of the comparing result. The computer device classifies the detected abnormality of the optical members into a plurality of abnormal modes corresponding to the comparing result of the photographed image and the reference image.
