This is a method of manufacturing a sheet like member having a low expansion region and a high expansion region. SeaElastic member between opposed surfaces of the continuum of the base sheet of the trate memberThe step of disposing the continuous body (35a) in the stretched state and the continuum of the rotating bodyThe conveying process is carried out on the surface (61 as) and the continuous body is positioned at a predetermined positionA production process is provided for cutting the substrate sheet by cutting in C). In the transport processA junction portion (J) for joining the opposed surfaces is applied to the high expansion / contraction corresponding region of the continuum (a)The outer peripheral surface of the continuum of the elastic member at both sides in the CD direction at H1A cutter blade of the outer peripheral surface is formed in the convex portion of the outer peripheral surface (al1) of the outer peripheral surfaceThe continuous member of the elastic member is cut to produce an intermediate body (35 m) of the elastic member.In the production process, the intermediate body is also cut at the predetermined position to produce an elastic memberAfter that, the elastic member expanded in the CD direction is located on both sides of the CD directionThey are sandwiched between the junctions.低伸縮領域と高伸縮領域とを有したシート状部材の製造方法である。シート状部材（３１）に係る基材シートの連続体の対向面同士の間に、弾性部材の連続体（３５ａ）を伸長状態で配する工程と、前記連続体を回転体の外周面（６１ａｓ）に巻き付けて搬送する搬送工程と、前記連続体を所定位置（ＰＣ）で切断して基材シートを生成する生成工程と、を有する。搬送工程では、上記対向面同士を接合する接合部（ｊ）を、前記連続体の高伸縮対応領域（ＡＨ１）において前記弾性部材の連続体のＣＤ方向の両側の位置に前記外周面の凸部で形成し、低伸縮対応領域（ＡＬ１）では、前記外周面のカッター刃で前記弾性部材の連続体を切断して弾性部材の中間体（３５ｍ）を生成する。生成工程では、上記所定位置で前記中間体も切断して弾性部材（３５）を生成し、その後では、ＣＤ方向に拡大した前記弾性部材は、ＣＤ方向の両側の前記接合部同士で挟圧されている。
