PROBLEM TO BE SOLVED: To position a member to be positioned with a simpler structure.SOLUTION: A lower surface 17a of a slot die 17 for applying electrode material on a metal foil 11 of a lithium ion battery is provided with three of first, second, and third positioned parts 17A, 17B, 17C formed of recessed parts. Positioning bars 47 having spherical parts 45 on tip ends are moved by cylinder drive, and the spherical parts 45 are positioned in shallow parts 17j2, 17k2, 17m2 from deep parts 17j1, 17k1, 17m1 in the first, second, third positioned parts 17A, 17B, 17C, and the slot die 17 is raised from a pedestal 43. At this time, the spherical part 45 is in point contact with a left side surface side positioning surface 17j4 and a rear surface side positioning surface 17j5, which are orthogonal to each other in the first positioned part 17A, and the other spherical part 45 is in point contact with a right side surface side positioning surface 17k4 and a front part inclined surface side positioning surface 17k5 which are orthogonal to each other in the second positioned part 17B. |
