This is a method of manufacturing a sheet-like member in which a plurality of through holes h are formed from a sheet 30mf continuous in the conveying direction. A step of conveying the sheet 30mf inserted between the first nonwoven fabric 30mf1 and the second nonwoven fabric 30mf2 which are continuous with each other in the conveying direction and in which the plurality of elastic members 35a are arranged in the CD direction； and the sheet 30mf Step S50 of forming a through hole h in the sheet 30mf by pushing the member 55p into a position between the elastic members 35a and 35a adjacent to each other in the CD direction. In the step S50, after pressing the member 55p from the non-opposing surface 30mf1sn that does not oppose the second non-woven fabric 30mf2 out of both surfaces of the first non-woven fabric 30mf1, the member 55p is pulled out toward the non-opposing surface 30mf1sn. The non-facing surface 30mf1sn is a surface 30mf1s1 that comes into contact with the surface 202s when the constituent fibers are sucked and deposited on the support surface 202s of the support member 202 so as to generate the first nonwoven fabric 30mf1. 搬送方向に連続するシート３０ｍｆから複数の貫通孔ｈが形成されたシート状部材を製造する方法である。搬送方向に連続しつつ互いに重なった第１不織布３０ｍｆ１と第２不織布３０ｍｆ２との間に、複数の弾性部材３５ａがＣＤ方向に並んだ状態で介挿されたシート３０ｍｆを搬送する工程と、シート３０ｍｆにおいてＣＤ方向に隣り合う弾性部材３５ａ，３５ａ同士の間の位置に部材５５ｐを押し込むことで、シート３０ｍｆに貫通孔ｈを形成する工程Ｓ５０と、を有する。同工程Ｓ５０では、第１不織布３０ｍｆ１の両面のうちで第２不織布３０ｍｆ２と対向しない非対向面３０ｍｆ１ｓｎから部材５５ｐを押し込んだ後に、同部材５５ｐを非対向面３０ｍｆ１ｓｎの方へ引き抜く。非対向面３０ｍｆ１ｓｎは、第１不織布３０ｍｆ１を生成すべくその構成繊維を支持部材２０２の支持面２０２ｓに吸引して堆積させた際に、同面２０２ｓに当接した方の面３０ｍｆ１ｓ１である。
