A manufacturing method for manufacturing a laminate by laminating a thermoplastic film on a first sheet and a second sheet at a joining part after a pass line forming process of forming a pass line for a film-formed film raw material, the film raw material becoming the thermoplastic film, the pass line forming process comprising: a hanging-down step of causing a resin in a molten state to hang down from a discharge port of a discharger, the resin becoming the film raw material, and the hanging-down step continuously discharging the film raw material; a first conveying step of conveying the first sheet in a lateral or oblique lateral direction along a first sheet pass line below the discharge port; a receiving step of receiving a tip part of the film raw material with the first sheet on the first sheet pass line, the tip part being discharged and hanging down from the discharge port; a second conveying step of conveying the first sheet and the film raw material after the tip part overlaps the first sheet on the first sheet pass line, the second conveying step conveying the first sheet and the film raw material in a mutually overlapping state along the first sheet pass line; and an introducing step of introducing the first sheet and the film raw material in the mutually overlapping state to the joining part from the first sheet pass line, wherein the thermoplastic film is an elastomer film and the film raw material is a film-formed pre-elastomer, wherein the first sheet and the elastomer film are conveyed in an overlapping manner along an outer peripheral surface of a bonding roll (Ar) serving as the joining part and a bonding step is performed on the bonding roll (Ar), the first sheet and the second sheet made of nonwoven fabric are supplied to the bonding roll (Ar), the first sheet and the second sheet are supplied to the bonding roll (Ar) along the first sheet pass line and a second sheet pass line, respectively, the elastomer film is introduced to the bonding roll (Ar) while being sandwiched by the pair of sheets (S1, S2), and the pair of sheets (S1, S2) and the elastomer film are bonded to and laminated with each other on the bonding roll (Ar) by an ultrasonic horn to produce the laminate. a hanging-down step of causing a resin in a molten state to hang down from a discharge port of a discharger, the resin becoming the film raw material, and the hanging-down step continuously discharging the film raw material; a first conveying step of conveying the first sheet in a lateral or oblique lateral direction along a first sheet pass line below the discharge port; a receiving step of receiving a tip part of the film raw material with the first sheet on the first sheet pass line, the tip part being discharged and hanging down from the discharge port; a second conveying step of conveying the first sheet and the film raw material after the tip part overlaps the first sheet on the first sheet pass line, the second conveying step conveying the first sheet and the film raw material in a mutually overlapping state along the first sheet pass line; and an introducing step of introducing the first sheet and the film raw material in the mutually overlapping state to the joining part from the first sheet pass line, wherein the thermoplastic film is an elastomer film and the film raw material is a film-formed pre-elastomer, wherein the first sheet and the elastomer film are conveyed in an overlapping manner along an outer peripheral surface of a bonding roll (Ar) serving as the joining part and a bonding step is performed on the bonding roll (Ar), the first sheet and the second sheet made of nonwoven fabric are supplied to the bonding roll (Ar), the first sheet and the second sheet are supplied to the bonding roll (Ar) along the first sheet pass line and a second sheet pass line, respectively, the elastomer film is introduced to the bonding roll (Ar) while being sandwiched by the pair of sheets (S1, S2), and the pair of sheets (S1, S2) and the elastomer film are bonded to and laminated with each other on the bonding roll (Ar) by an ultrasonic horn to produce the laminate.
