PURPOSE:To efficiently obtain a bag-shaped mat by forming projections on the side facing a welding born for joining when a mat-shaped mat is joined in a bag shape. CONSTITUTION:Projections are formed on the side (anvil) 8 facing a horn 7 for ultrasonic wave or thermal adhesion to press a mat-shaped separator 3 from the upper and lower sides. The projections enter the separator, and heat is passed between the horn 7 and the anvil 8, and the separator 3 made of thermoplastic synthetic fibers is formed in a bag. By forming the separator 3 in a gag with thermoplastic synthetic resin, an opening part of the end of electrode can be removed.
