Summary:To improve the detection precision and detection efficiency and further to automatize the detection process, moisture in a honeycomb panel (1) is detected as follows: the honeycomb panel (1) is heated by a lamp (3); the surface temperature of the heated construction is measured by an infrared radiation thermometer (2); the measured temperature is displayed to roughly discriminate an abnormal portion; the honeycomb panel (1) is further heated continuously to detect temperature-change-rates at both abnormal and normal portions; and the two temperature-change-rates are compared with each other to discriminate a presence of moisture.
