PROBLEM TO BE SOLVED: To enable a defect of even a moving flaw detection object to be detected, in a flaw detection system for detecting a defect such as a flaw existing in the flaw detection object or peeling thereof by measuring the surface temperature of the heated flaw detection object.SOLUTION: The flaw detection system includes: a halogen light 12 for continuously heating, at a predetermined heating position, a flaw detection object Z that relatively moves at a predetermined speed; an infrared camera 11 for acquiring the heat quantity of the heated flaw detection object in time series at a heat quantity acquisition position separate from the heating position by a predetermined distance on the downstream side of the heating position in the relative moving direction; a control unit 16; and a display unit 18 for displaying a defect existing in the flaw detection object on the basis of the time-series heat quantity at the heat quantity acquisition position.SELECTED DRAWING: Figure 1
