    摘要： A positive electrode for a nonaqueous battery includes a double-coated part (14) including a positive electrode active material layer (13) formed on each surface of a current collector core (12), a core exposed part (18) which is located at an end of the current collector core (12), and does not include the positive electrode active material layer (13), and a single-coated part (17) which is located between the double-coated part (14) and the core exposed part (18), and includes the positive electrode active material layer (13) formed only on one of the surfaces of the current collector core (12). A plurality of grooves (10) are formed in each surface of the double-coated part (14) to be inclined relative to a longitudinal direction of the positive electrode (2), while the grooves are not formed in the single-coated part (17). A positive electrode current collector lead (20) is connected to the core exposed part (18). The positive electrode (2) is wound in such a manner that the core exposed part (18) constitutes a last wound end, or the positive electrode (2) is accordion-folded in such a manner that the core exposed part (18) constitutes an outermost layer.
