Zusammenfassung:	PURPOSE:To obtain the titled high-silicon iron sheet in which occurrence of surface cracks at the time of assembly working is inhibited and deterioration in magnetic properties due to cracking is properly prevented, by incorporating prescribed percentage of Si and also by specifying the ratio of fluctuation in sheet thickness in the direction of sheet width to average sheet thickness and the degree of flatness in the longitudinal direction of sheet, respectively. CONSTITUTION:A high-silicon steel sheet which contains 4-7wt% Si and in which fluctuation in sheet thickness in the sheet-width direction is regulated to + or -10% of the average sheet thickness or less and also the degree of flatness in the longitudinal direction of sheet is specified to
