Claim:
1. A nondestructive inspection apparatus of a structure, comprising: an infrared light irradiation unit configured to irradiate a structure to be inspected with heating infrared light, and is independently rotatable about a horizontal rotation shaft; a temperature variation measuring unit configured to measure a variation in temperature of the structure due to the irradiation with infrared light from the infrared light irradiation unit, and is independently rotatable about the horizontal rotation shaft; a drive-control-and-accumulation unit configured to perform drive control of the infrared light irradiation unit and the temperature variation measuring unit and configured to perform data accumulation; and a self-running mechanism unit that enables a casing, on which the infrared light irradiation unit, the temperature variation measuring unit, and the drive-control-and-accumulation unit are mounted, to move along the structure, wherein the structure is configured to be inspected for an internal defect by irradiating the structure with heating infrared light while the nondestructive inspection apparatus moves along the structure to be inspected through the use of the self-running mechanism unit and measuring the variation in temperature of the structure due to the irradiation with infrared light.
