In the battery 10, a positive electrode member 20 in which a positive electrode mixture layer 22 is formed on one side of a positive electrode current collector 21, a separator 40 containing an electrolyte, and a negative electrode mixture layer 32 on one side of a negative electrode current collector 31. Laminates 12A and 12B in which the negative electrode members 30 are stacked and the positive electrode mixture layer 21 and the negative electrode mixture layer 31 are disposed to face each other are stacked such that a plurality of current collectors of the same polarity face each other. And an exterior member 50 for covering the laminated structure 11. The exterior member 50 has a Young's modulus of 3 × 10 9 Pa or more, preferably 4 × 10 9 Pa or more. At least the resin layer 51 is provided. |
