A dresser board (11) for use in correcting a shape of a cutting blade (14) includes a first layer (13) including first abrasive grains and a first binding material that holds the first abrasive grains, and a plurality of second layers (15) stacked on the first layer (13) in sandwiching relation thereto. A thickness of the first layer (13) is smaller than a width of the cutting blade (14), and the second layer (15) includes second abrasive grains whose average diameter is smaller than that of the first abrasive grains and a second binding material that holds the second abrasive grains.
