PROBLEM TO BE SOLVED: To enhance the electric contact state of a solid electrolyte with a positive electrode active material layer and a negative electrode active material layer and provide an ideal distance between particles within the positive electrode active material layer and the negative electrode active material layer to improve the load characteristic by impregnating the solid electrolyte dissolved in a solvent on an active material layer. SOLUTION: This battery has a positive electrode plate 1 having a positive electrode active material layer 1b and a solid electrolyte layer 1c formed on a positive electrode current collector 1a, and a negative electrode plate 2 having a negative electrode active material layer 2b and a solid electrolyte layer 2c formed on a negative electrode current collector 2a. The solid electrolyte layer 1c is formed on the positive electrode active material layer 1b, and the solid electrolyte layer 2c is formed on the negative active material layer 2b. The solid electrolyte layer 1c, 2c is formed by impregnating a solid electrolyte in the positive electrode active material layer 1b or the negative electrode active material layer 2b, respectively. By impregnating the solid electrolyte in the active material layer, the internal resistance of the battery can be reduced, and the contact state between the active material and the solid electrolyte can be improved. |
