A method of manufacturing an absorbent article having an elastic film stretchable structure that includes a stretchable region stretchable in one direction, the method comprising: in forming the elastic film stretchable structure, forming sheet bonded portions by bonding a first sheet layer and a second sheet layer directly or through an elastic film at a large number of positions arranged at intervals in a state in which the elastic film is interposed between the first sheet layer and the second sheet layer while being stretched in a stretchable direction of the stretchable region; and as the elastic film,using an elastic film on which a design printing portion is printed in advance in a portion to be the stretchable region, or printing the design printing portion in the portion to be the stretchable region in the elastic film in manufacturing line, prior to stretching of the elastic film, further comprising: in forming the elastic film stretchable structure, forming the sheet bonded portions by bonding directly the first layer sheet and the second layer sheet by ultrasonic sealing, which is performed with the first sheet layer, the elastic film, and the second sheet layer passed between an anvil roll and an ultrasonic horn in the state in which the elastic film is interposed between the first sheet layer and the second sheet layer while being stretched in the stretchable direction of the stretchable region; and supplying the elastic film such that the design printing portion is disposed in a surface of the elastic film, the surface being on a side opposite to the anvil roll side. in forming the elastic film stretchable structure, forming sheet bonded portions by bonding a first sheet layer and a second sheet layer directly or through an elastic film at a large number of positions arranged at intervals in a state in which the elastic film is interposed between the first sheet layer and the second sheet layer while being stretched in a stretchable direction of the stretchable region; and as the elastic film,using an elastic film on which a design printing portion is printed in advance in a portion to be the stretchable region, or printing the design printing portion in the portion to be the stretchable region in the elastic film in manufacturing line, prior to stretching of the elastic film, further comprising: in forming the elastic film stretchable structure, forming the sheet bonded portions by bonding directly the first layer sheet and the second layer sheet by ultrasonic sealing, which is performed with the first sheet layer, the elastic film, and the second sheet layer passed between an anvil roll and an ultrasonic horn in the state in which the elastic film is interposed between the first sheet layer and the second sheet layer while being stretched in the stretchable direction of the stretchable region; and supplying the elastic film such that the design printing portion is disposed in a surface of the elastic film, the surface being on a side opposite to the anvil roll side. in forming the elastic film stretchable structure, forming the sheet bonded portions by bonding directly the first layer sheet and the second layer sheet by ultrasonic sealing, which is performed with the first sheet layer, the elastic film, and the second sheet layer passed between an anvil roll and an ultrasonic horn in the state in which the elastic film is interposed between the first sheet layer and the second sheet layer while being stretched in the stretchable direction of the stretchable region; and supplying the elastic film such that the design printing portion is disposed in a surface of the elastic film, the surface being on a side opposite to the anvil roll side.
