PROBLEM TO BE SOLVED: To efficiently perform chamfering machining with a high working precision while restraining lowering of yield when performing chamfering of the corner of a glass substrate. SOLUTION: The device for chamfering the corner of the glass substrate 1 is equipped with a whetstone 19 provided with a recess 19c including a pair of grinding faces 19a, 19b which face each other and are inclined in different directions, a support member 9 and a pair of clamping members 5, 6 which hold a plurality of rectangular glass substrates 3 at intervals in the direction of a board thickness and movably hold the whetstone 19 in the direction of a board thickness in the positional relationship that a pair of grinding faces 19a, 19b respectively touch two corners 3a, 3b on both ends of one side of the individual glass substrate 3, a whetstone movable frame 20 which reciprocatively moves the whetstone 19 held by the support member 9 and the clamping members 5, 6 together with the glass substrate 3 in the direction of board thickness (arrow Y1-Y2 direction), actuators 7, 8, and a control part 2.
