<P>PROBLEM TO BE SOLVED: To provide a method capable of manufacturing a wound electrode body with adequate hardness in a situation that the quick acceleration and deceleration of winding speed is generated. <P>SOLUTION: The manufacturing method for a wound electrode body is a method wherein beltlike electrodes 11, 13 and beltlike separators 12, 14 are wound by overlapping each other in order to manufacture the wound electrode body, and has a process of winding the beltlike electrodes 11, 13 and the beltlike separators 12, 14 into a winding shaft 20 while pushing the pushing member 30. A pushing force of the pushing member 30 is enlarged in proportion to the reduction of tension T acting on at least one of the beltlike electrodes 11, 13 and the beltlike separators 12, 14. <P>COPYRIGHT: (C)2010,JPO&INPIT |
