The peak shift and line broadening on 0.66%C steel deformed by tension were measured by means of X-ray diffractometer. These values depended on their diffraction plane. In this paper, the change in peak shift and line broadening on the diffraction line was discussed with reference to its elastic anisotropy. The results are as follows. (1) The change in park shift on the diffraction line was accounted for by considering that the mean residual stress in the grains in which X-ray diffraction occurred was constant. (2) Also the change in line broadening was accounted for by considering that the distribution of micro-stresses in each grain or between the grains in which X-ray diffraction occurred was almost the same. (3) It seems that it was either because the principal stresses in each grain were r_1≒r_2, or because the specimen in this work and texture, that there was but little line broadening due to the difference in the direction of action of the principal stresses. (4) The mean residual stresses measured from peak shift agreed with that which was obtained by the sin^2ψmethod.
