• 0.0010 mass % or less, V:
• 0.0050 mass % or less, and O:
• 0.0050 mass % or less, with the balance being Fe and unavoidable impurities,
• characterized in that
• when an alternating-current magnetic field with a frequency of 50 Hz and a maximum magnetic flux density Bm of 1.5 T is applied in a rolling direction (RD), a sheet width direction (TD), and a direction (DD) forming an angle of 45° with the rolling direction, in a rolling plane of the steel sheet, and zero-peak values of resulting magnetostrictions in directions parallel to the respective magnetic field directions are represented as λ//HRD, λ//HTD, and λ//HDD, respectively, a magnetostriction in-plane average value λ//Have defined by the following Formula (1) is 1.0×10−5 or smaller.
