Since the method of X-ray stress measurement can be done by non-contact and non-destructive state, we can easily perform the measurement even if the temperature is high such as a few hundreds degree. In this paper the thermal stress on heated clad steel by X-ray was measured. The result was that we could perform good stress measurement and could find a clear thermal stress cycle at even such a high temperature as 560℃. Experimental results are as follows : 1) The clad steel hearted up to a temperature of 560℃ showed a fine X-ray profile and gave a good correlation on 2θ-sin^2φ diagrams, so we could perform thermal stress measurement by the usual method. 2) In the heating process the thermal stress explained by thermal-expansion coefficient showed thermal stress explained by thermal-expansion coefficient showed thermal stress cycles, giving a terperature loop. 3) The stress value varied by removal of oxide film.
