A ferritic steel sheet wherein a mean value of X-ray random intensity ratios of a group of ä100ü<011> to ä223ü<110> orientations is 3.0 or more and a mean value of X-ray random intensity ratios of three crystal orientations of ä554ü<225>, ä111ü<112>, and ä111ü<110> is 3.5 or less and further at least one of the r values in a rolling direction and a direction at a right angle of that is 0.7 or less. <IMAGE>
