Abstract

Provided is an absorbent article which includes a top sheet having extruded protrusions and a second sheet bonded to the top sheet and has adequate softness, satisfactory appearance, and yet prevents wrinkles in the top sheet along the MD. The problem is solved by a method of producing an absorbent article including forming the extruded protrusions through embossing of non-woven fabric to be a top sheet transferred by being drawn from downstream of a production line; and then bonding the non-woven fabric and a material of a second sheet in a bonding pattern formed by aligning the material of the second sheetwith the back face of the non-woven fabric having extruded protrusions, forming rows of plurality of top-second bonded portions at intervals in the CD in regions between the extruded protrusions adjacent each other in the MD so as to be provided across the center positions of the regions in the CD, and compressing the non-woven fabric in areas between the top-second bonded portions in the rows in the CD without welding of the non-woven fabric and the material of the second sheet.
