摘要：
A negative-electrode active material layer 12 contains Li4Ti5O12 as a negative-electrode active material, and a positive-electrode active material layer 14 contains LiCoO2 as a positive-electrode active material. A solid electrolyte layer 13 contains polyethylene oxide and polystyrene as an electrolyte material. Gradients of surfaces of stripe-shaped pattern elements 121 forming the negative-electrode active material layer 12 are smaller than 90° when viewed from a surface of the negative-electrode current collector 11. By such a construction, it is possible to construct a battery having a high capacity in relation to the used amount of the active materials and good charge and discharge characteristics.
