摘要： A silicon-containing steel sheet having a low iron loss has such a crystal structure that crystal grains having an inclination angle of {110} face of not more than 10.degree. with respect to the sheet surface are included in an amount of not less than 80 vol % and exhibit a graining surface pattern in which boundaries of these crystal grains form stepwise difference or groove of not less than 0.4 .mu.m as a maximum height. This sheet is produced by subjecting a grain oriented silicon steel sheet after final annealing to a magnetically smoothening treatment by electrolysis in an squeous solution containing at least one of water soluble halides.
