The ductile damage progress of the FCC single crystal was verified by the profile analysis using the white X-ray obtained in BL28B2 beam-line of SPring-8. In this study, an aluminum single crystal of the purity 6N was used as a specimen prepared in the I-type geometry for tensile test. The notch was introduced into one side of the center of a parallel part of the specimen by wire electric discharge machining. White X-ray, which has 200 microns in height and 100 microns in width, was incident into the specimen on the Bragg angle of 3$$^{circ}$$ in the horizontal plane using energy dispersive X-ray diffraction technique. As a result, in 1.1% of applied strain, increase of the lattice strain was observed in the direction of about 45$$^{circ}$$ of slant from the notch bottom. In 2.2% of applied strain, the lattice strain reduced in the direction of about 45$$^{circ}$$ of slant from the notch bottom. Non-uniform strain and dislocation density decreased similarly.
