PROBLEM TO BE SOLVED: To provide a nondestructive inspection device capable of inspecting a defect on an inner face of a cylindrical body such as a cylinder, in a short time, and allowing thereby in-line total inspection. SOLUTION: This nondestructive inspection device 100 for inspecting nondestructively the defect on the inner face of the cylinder 200 is provided with a conical type omnidirectional mirror 101 inserted into an inside of the cylinder 200, a xenon tube 102 for applying a pulse-like heat load onto the inner face of the cylinder 200, an infrared camera 103 for measuring a temperature distribution of the inner face of the cylinder 200 just after the heat load is applied, via the conical type omnidirectional mirror 101, by an infrared thermography, and an analyzer 104 for analyzing the temperature distribution measured by the infrared camera 103 to specify the defect.
