PROBLEM TO BE SOLVED: To provide a hot dip galvannealed steel sheet in which the pattern development of the defect on a stripe is suppressed. SOLUTION: This steel sheet has a composition containing <=0.004% C, <=0.1% Si, <=0.5% Mn, <=0.025% P, <=0.025% S and 0.005 to 0.100% Al or further containing one or more kinds metals selected from 0.015 to 0.04% Ti and 0.001 to 0.010% Nb and has a hot dip galvannealing layer in which, as to the surface structure of the steel sheet by X-ray diffraction, the ratio in diffraction X-ray intensity between that from the 200} plane and that from 222} plane, i.e., I(200)/I(222) is 0.17, and also, the deviation in the sheet face is±5 g/m2.
