PROBLEM TO BE SOLVED: To provide a method for producing a cellular sheet fine in temperature control, pressure control and many stripe-like cells produced upon pasting a plurality of films by a pressure roll or the like, and to provide the cellular sheet. ! SOLUTION: A pushing up projection part 235 is provided at a part as the outer circumferential face of a vacuum molding roll 23 being a part located between cavities 232, and when a back film 12 is tightly adhered with a cap film 11 rounded around the vacuum molding roll 23 by static electricity, the specific part of the cap film 11 pushed up by the pushing up projection part 235 is fused to the back film 12 prior to the other parts, thus stripe-shaped cells 15 are formed. !
