PROBLEM TO BE SOLVED: To grind a peripheral edge of a thin plate having recessed parts or projecting parts on its peripheral edge with high accuracy. SOLUTION: This peripheral edge grinding device for a thin plate has a wheel spindle inclining mechanism 1 capable of changing an inclination angle of a rotating spindle of a grinding wheel 3 to a rotating spindle of the thin plate 2, and further changing its inclining direction. Accordingly, the chamfering work (grinding work) can be executed on the recessed parts and the projecting parts of the peripheral edge with high accuracy similarly as an outer peripheral part of the thin plate by changing the inclining direction while keeping the inclination angle.
