摘要

A battery electrode plate is provided with a double-side coated section (14) whereupon active material layers (13) are formed on the both surfaces of a power collection core material (12); a core material exposing section (18), which is an end section of the power collection core material (12) and does not have the active material layer (13) formed thereon; and a single-side coated section (17), which is arranged between the double-side coated section (14) and a core material exposing section (18), and has the active material layer (13) formed only one surface of the power collection core material (12). A plurality of groove sections (10) are formed on the both surfaces of the double-side coated section (14), and the groove section (10) is not formed on the singe-side coated section (17).
