PROBLEM TO BE SOLVED: To provide a steel band surface grinding device and method for surely preventing the excessive grinding at the end of a steel band even when the steel band has a great plate thickness deviation in the cross direction before ground. SOLUTION: The steel band surface grinding device comprises a plurality of steel band surface grinders consisting of contact rolls and billy rolls on which a pair of grinding belts are wound. The first steel band surface grinder has the billy roll arranged around a position equivalent to 1/5 to 1/3 of a roll shaft from one roll end in inclination of an angle ofθto the contact roll on a horizontal plane in the proceeding direction of the steel band and the second steel band surface grinder has the billy roll arranged around a position equivalent to 2/3 to 4/5 of the roll shaft from the roll end in inclination of an angle of -θto the contact roll on the horizontal plane in the proceeding direction of the steel band are continuously installed in at least one pair.
