摘要 |
An electrode plate includes a both-surface coated part 14 in which an electrode active material layer 13 is provided on both surfaces of a current collector core material 12, a core material exposed part 18 in which the negative electrode active material layer 13 is not provided, and a one-surface coated part 17 in which the negative electrode active material layer 13 is provided on only one surface of the current collector core material 12. A plurality of grooves 10 are formed in both surfaces of the both-surface coated part 14 and the grooves 10 are not formed in the one-surface coated part 17.
