PROBLEM TO BE SOLVED: To facilitate changing the combination of two or more concave blades, while reducing a manufacturing cost of the concave blade. SOLUTION: In a scoring device which forms a score on a sheet of paper by holding the conveyed paper between a scoring member 121 and a support base 122, the support base 122 includes a concave member which is formed by symmetrically arranging two rectangular parallelepiped members 171a, 171b with the same cross-sectional shape and adhering their flanks. In the concave member, when a taper surface is formed by chamfering at a corner part in a longitudinal direction of the rectangular parallelepiped, and flanks of both members are adhered, a scoring groove 122a is formed by facing taper surfaces. Rotation of two members 171a, 171b changes the combination of the facing taper surfaces, and thereby allowing the scoring groove 122a corresponding to paper thickness to be selected.
