摘要

A negative-electrode active material layer formed between a negative-electrode current collector (11) and a solid electrolyte layer (13) has a line-and-space structure in which a plurality of stripe-shaped pattern elements (121) extending in a Y direction are arranged while being separated from each other. A gradient ¸ at each contact point P where the stripe-shaped pattern element (121), the negative-electrode current collector (11) and the solid electrolyte layer (13) are in contact with each other is made smaller than 90°.
