To provide an inspection device of a bent article, capable of automatically and easily inspecting presence of cracking on a bent article of an oblong metal body made from conductive material.

The inspection device includes an inspection bed 2 on which a bent article 1 of an oblong metal body made from conductive material is carried. The inspection bed 2 includes a positioning member 4 for positioning a reference part 1A of the bent article 1, and detection members 5 and 6 for detecting displacement of a comparison part of the bent article. A controller 12 is provided which issues an alert when the detection members 5 and 6 detect displacement of a comparison part 1B of the bent article 1. If a bending process by a bending device is too strong to cause cracking and the position of the comparison part 1B comes out of a tolerable range, the detection members 5 and 6 detect this, and the controller 12 issues an alert, thus presence of cracking of the bent article 1 can be automatically and easily inspected.
