The present invention provides a method for producing a composite sheet for an absorbent article by bonding a continuum of elastic band members to a continuous body of sheets continuously conveyed in the conveying direction with a predetermined meandering pattern. A first joining step of joining the first elastic band member and the first elastic band member while the first elastic band member is in surface contact with the first elastic band member through the first swinging arm swinging in a direction intersecting with the conveying direction with the first support shaft part as a turning center, And a second joining step of joining the second elastic band members to each other while the second elastic band members are conveyed to the sheet surface by surface contact through a second swinging arm swinging in a direction intersecting with the conveying direction with the shaft part as a turning center. In the first joining step, the first elastic band member supplied toward the first support shaft side rollers of the first swinging arm is in contact with the outer peripheral surface of the first support shaft side roller and the outer peripheral surface of the first swinging end side roller of the first swinging arm And is turned on and inverted in the proceeding direction, and then put on the sheet to be joined. In the second joining step, the second elastic band member supplied toward the second supporting shaft side roller of the second swinging arm is in turn pressed against the outer peripheral surface of the second supporting shaft side roller and the outer peripheral surface of the second swinging end side roller of the second swinging arm And is turned on and inverted in the proceeding direction, and then put on the sheet to be joined. The first loading position for loading the first elastic band member onto the sheet by the first swinging arm and the second loading position for loading the second elastic band member onto the sheet by the second swinging ar
