The present invention provides a shearing die having longer life and a method for manufacturing the same. The invention provides a shearing die (1) comprising a pair of substrates, which is used for shearing a sheet or plate material (2) disposed therebetween by the pair of substrates, wherein a hard film formed by an arc ion plating method is provided at least on a region of a curved surface and a region from the end part of the curved surface on the side facing to the surface of the sheet or plate material 2 to 300 [mu]m along the surface of the substrate, of the surface of at least one of the substrate, and the hard film comprises Al and one or more of Ti and Cr, and has a thickness of 1 to 5 [mu]m, and the number of a metal particle having a diameter of 20 [mu]m or more, which is present on a line segment having a length of 10 mm on a surface of the hard film formed on region of the curved surface and the region from the end part of the curved surface on the side facing to the surface of the sheet or plate material (2) to 300 [mu]m along the surface of the substrate, is 2 or less.
