Abstract
A method for producing an absorbent article includes: while conveying non-woven fabric to be a top sheet by drawing from the downstream side, forming extruded projections by embossing; placing a material for a second sheet on the back surface of the non-woven fabric with the extruded projections; and joining the non-woven fabric and material for the second sheet in a joint pattern in which top-second joint portions are formed between the MD direction adjacent extruded projections at CD direction central positions corresponding to CD direction central portions of the adjacent extruded projections and at lateral positions on the CD direction both sides of the central positions. A MD direction joint range of the top-second joint portions is wider continuously or stepwise with increasing proximity from the central position to the lateral sides. This allows joining a top sheet having extruded projections and a second sheet while preventing occurrence of MD direction wrinkles in the top sheet.
