Provided is a die-cutting blade capable of forming smooth die-cut lines in case-forming blanks which are less likely to injure hands, even if these case-forming blanks are touched by the hands. A strip-plate-shaped blade plate (10) made of a steel plate is provided with a pair of chamfers (11) formed on the opposite side surfaces of the blade plate, respectively, so as to extend from one side edge of the blade plate at substantially equal inclination angles. The chamfers (11) define a cutting edge (12) along the one side edge. The cutting edge (12) has a composite wave pattern formed from a small wave pattern (12a) which is bent to have a wave shape within the range of the thickness of the blade plate (10), and a large wave pattern (12b) formed by a large undulation in the small wavy edge (12a) toward the opposite side surfaces of the blade plate over the entire length thereof within the range of the thickness of the blade plate (10), in order to provide smooth die-cut lines.
