Provided is a method for producing a sheet-like member having an elastic member (35) attached thereto in which a continuous body (35a) of an elastic member is inserted between a pair of facing surfaces of continuous bodies of a sheet-like member along a conveyance direction and the continuous bodies of the sheet-like member and the continuous body (35a) of the elastic member are subsequently cut at a position to be cut (PC). The method for producing a sheet-like member comprises a formation step in which the facing surfaces having the continuous body (35a) of the elastic member inserted therebetween are joined by joining sections (j) and a cutting step in which the sheet-like member and the elastic member (35) are created by cutting at the position (PC). In the formation step, the joining sections (j) are formed on both sides of the continuous body (35a) of the elastic member in a CD direction while the continuous body (35a) of the elastic member is extended in the conveyance direction. The elastic member (35) expands in the CD direction and is sandwiched in the CD direction by the joining sections (j, j) on both sides and attached to the sheet-like member after the cutting step. One of the facing surfaces is a nonwoven fabric. This surface is a non-contact surface that is not brought into contact with constituent fibers when said constituent fibers are suctioned and accumulated on a support surface of a support member in order to create the nonwoven fabric.L'invention concerne un procédé de production d'un élément stratiforme comprenant un élément élastique (35) fixé à celui-ci dans lequel un corps continu (35a) d'un élément élastique est inséré entre une paire de surfaces en regard de corps continus d'un élément stratiforme le long d'une direction de transport et les corps continus de l'élément stratiforme et le corps continu (35a) de l'élément élastique sont ensuite découpés dans une position à découper (PC).
