Patent ID: 7842418

Claim:
An electrode plate for a nonaqueous battery, in which an active material layer is formed on a surface of a current collector core material, the electrode plate comprising: a both-surface coated part in which the active material layer is formed on both surfaces of the current collector core material; a core material exposed part which is an end part of the current collector core material and in which the active material layer is not formed; and a one-surface coated part which is provided between the both-surface coated part and the core material exposed part and in which the active material layer is formed on only one of surfaces of the current collector core material, wherein a plurality of grooves are formed in both surfaces of the both-surface coated part so as to be tilted from a longitudinal direction of the electrode plate and are not formed in the one-surface coated part, and the electrode plate is obtained by cutting an electrode plate hoop material including the both-surface coated part, the one-surface coated part and the core material exposed part being continuously formed in this order at the core material exposed part provided between the both-surface coated part and the one-surface coated part.
