Abstract:
This electrode plate 21 comprises: a band-shaped core 22 having a first main surface 23 and a second main surface 24; and an active material layer 27 formed on each of the first main surface 23 and the second main surface 24. The core 22 has a both-sides-coated part 25 in which the active material layer 27 is formed on both the first main surface 23 and the second main surface 24, and an exposed part 26 which is provided contiguously with the both-sides-coated part 25 and in which the active material layer 27 is not formed on at least the first main surface 23. The first main surface 23 in the exposed part 26 has an identification display part 28 formed in a region within 90% of the way toward the center in the width direction of the core 22. In this way, it is possible to highly precisely form the identification display part.
