摘要： PROBLEM TO BE SOLVED: To enable a process in which a precursor sheet is manufactured simply with good operability by a method in which a polymer film layer and a nonwoven fabric layer are laminated in a nonstretching state on a cooling molding part, the laminate is cooled, and in both end parts of the breadth direction, both layers are cemented in the longitudinal direction. SOLUTION: An expandable/shrinkable polymer film (a) discharged from a die 1 is laid for example with a nonwoven fabric (b) which is expandable in the cross direction to overlap a cooling molding part which is formed by a cooling roll 2 and a nip roll 3 to be introduced so that the film (a) layer comes to the side of the roll 2 and the fabric (b) layer comes to the side of the roll 3. In the cooling molding part, both end parts in the breadth direction of the roll 3 are pressed by two protruding belts which are installed in both end parts to surround the whole peripheral surface, the film (a) layer, which is still kept adhesive, is cemented to the fabric (b) layer in both end parts in the breadth direction, and the inside part between the protruding belts is made nonadhesive.
