A plurality of pushing members 55p provided as members separate from the rotating body 52 while projecting to the outside of the outer peripheral surface of the rotating body 52 rotating around the rotation axis C52 along the CD direction are used as the rotation direction Dc52 of the rotating body 52. It is the apparatus 50 which forms the several hole part h in the said sheet-like member 1m by pushing into the sheet-like member 1m conveyed along. The rotating body 52 is provided on the center side portion 52in including the rotation axis C52, and on the outer side of the rotation radius direction Dr52 of the rotating body 52 than the center side portion 52in, and the pushing member 55p is inserted into the center side portion 52in. An outer peripheral side portion 52ex for holding the pressing member 55p so that the pressing member 55p contacts, and a heating element 54 provided in the central side portion 52in for heating the pressing member 55p via the central side portion 52in, Have A gap G52 in the rotational radius direction Dr52 is provided between the center side portion 52in and the outer peripheral side portion 52ex.ＣＤ方向に沿った回転軸Ｃ５２回りに回転する回転体５２の外周面の外側に突出しつつ前記回転体５２とは別部材として設けられた複数の押し込み部材５５ｐを、前記回転体５２の回転方向Ｄｃ５２に沿って搬送されるシート状部材１ｍに押し込むことにより、前記シート状部材１ｍに複数の孔部ｈを形成する装置５０である。前記回転体５２は、前記回転軸Ｃ５２を含む中心側部分５２ｉｎと、前記中心側部分５２ｉｎよりも前記回転体５２の回転半径方向Ｄｒ５２の外側に設けられ、前記中心側部分５２ｉｎに前記押し込み部材５５ｐが当接するように前記押し込み部材５５ｐを保持するための外周側部分５２ｅｘと、前記中心側部分５２ｉｎ内に設けられて前記中心側部分５２ｉｎを介して前記押し込み部材５５ｐを加熱する発熱体５４と、を有する。前記中心側部分５２ｉｎと前記外周側部分５２ｅｘとの間には、前記回転半径方向Ｄｒ５２の隙間Ｇ５２が設けられている。
