Problem to be solved: to provide a perforating roller provided with a pin on the outer periphery and a perforating roller for increasing the perforability to the nonwoven fabric by the counter roller.The perforation roller is provided with a perforation member 80 having a tip portion 81 which is pierced into a nonwoven fabric to gradually spread the piercing hole and pierces the expansion hole, and is rotated in a predetermined rotation direction. The tip portion 81 of the perforation member 80 is positioned at the downstream side in the rotational direction of the perforating roller as the center of the cross section of each of the cross sections intersecting with each of the piercing holes gradually extends.Diagram【課題】外周にピンが設けられた穿孔ローラと対向ローラによる不織布への穿孔性を高める穿孔ローラを提供する。【解決手段】穿孔ローラは、不織布に突き刺して刺孔を徐々に拡げて拡孔を穿孔する先端部81を備えた穿孔部材80を外周部に備え、所定の回転方向に回転する。穿孔部材80の先端部81は、徐々に拡げられる刺孔のそれぞれと交差する断面それぞれの中心が突き刺し方向に向かうほど穿孔ローラの回転方向の下流側に位置する。【選択図】図4
