The elastic member (35) is attached by cutting the continuous member after inserting the continuous member (35a) of the elastic member between a pair of opposing surfaces of the continuous member of the sheet-like member continuous in the conveying direction. It is a method of manufacturing the obtained sheet-like member. A fixing step of fixing the stretched elastic member to the opposing surface with an adhesive (BD), a forming step of forming a joint (j) that joins a pair of opposing surfaces, and the sheet-like member A cutting step of generating the sheet-like member and the elastic member by cutting the continuous body and the continuous member of the elastic member. In the fixing step, the portion (35ae) that becomes the end portion (35e) of the elastic member in the continuous body of the elastic member is fixed to the facing surface with an adhesive. In the forming step, the joint portions are formed on both sides of the elastic member continuous body in the CD direction. In the cutting step, an elastic member that is to be expanded in the CD direction along with the cutting is clamped in the CD direction between the joint portions on both sides and attached to the sheet-like member.搬送方向に連続するシート状部材の連続体が有する一対の対向面同士の間に、弾性部材の連続体（３５ａ）を介挿後に、同連続体を切断して、弾性部材（３５）が取り付けられたシート状部材を製造する方法である。伸長状態の弾性部材の連続体を前記対向面に接着剤（ＢＤ）で固定する固定工程と、一対の対向面同士を接合する接合部（ｊ）を形成する形成工程と、前記シート状部材の連続体及び弾性部材の連続体を切断することで、前記シート状部材及び弾性部材を生成する切断工程と、を有する。固定工程では、弾性部材の連続体において弾性部材の端部（３５ｅ）となる部分（３５ａｅ）を、前記対向面に接着剤で固定する。形成工程では、接合部を、ＣＤ方向において弾性部材の連続体の両側に形成する。切断工程では、切断に伴いＣＤ方向に拡大しようとする弾性部材を、両側の接合部同士でＣＤ方向に挟圧してシート状部材に取り付ける。
