    摘要： Provided is a method for manufacturing a ribbon piece that allows suppressing a damage of a rotary die cutter. A method for manufacturing a ribbon piece of the present disclosure includes punching out a ribbon piece from a ribbon material using a rotary die cutter. The rotary die cutter includes a die roll and an anvil roll. The die roll includes a die roll body, and a cutting blade is formed to protrude on an outer peripheral surface of the die roll body. The anvil roll includes an anvil roll body, a groove is provided on an outer peripheral surface of the anvil roll body, and the cutting blade is engageable with the groove with a space. In the punching, the ribbon material is cut by engaging the cutting blade of the die roll body with the groove of the anvil roll body with a space and pressing the cutting blade of the die roll body onto the ribbon material while sandwiching and pressing the ribbon material between a die roll side elastic body disposed in both sides of a base portion of the cutting blade on the outer peripheral surface of the die roll body and both sides of the groove of the outer peripheral surface of the anvil roll body when the ribbon material is passed through between the die roll and the anvil roll.
