PROBLEM TO BE SOLVED: To perform the inspection of a key 2 in a short time by radiating a linear laser beam L to the surface formed by the irregular faces of a key crest section 2C to determine the quality of the key crest section 2C. SOLUTION: This inspection device for the key 2 has a support means 3 for supporting the key 2 in a vertically raised state, and a radiating means 4 for radiating the linear laser light L toward the surface formed by the irregular faces of the key crest section 2C along the key crest section 2C. The inspection device 1 further comprises a camera 5 for taking the image of the reflected light L' from the surface formed by the irregular faces of the key crest section 2C and a determination means 6 for processing the image of the reflected light L' taken by the camera 5 to determine the quality of the key crest section 2C.
