PURPOSE: To reconcile the strength and flexibility of a battery and enhance the utilizing value by housing a flexible generating element in a flexible housing means, and bonding resin films to the reverse surfaces of current collectors of positive electrode and negative electrode. CONSTITUTION: A positive current collector having a resin film 1 bonded to the reverse side of a surface having an active material arranged thereon, a positive electrode active material 3, a separator layer 4, a negative electrode active material layer 5, and a negative electrode current collector 6 having a resin film 7 bonded to the reverse surface are successively laminated, and housed in a bag-like housing means 8 formed of a laminated body of metal thin film and synthetic resin and sealed. A flexible core body consisting of a net structure, bored plate, or porous body consisting of synthetic resin or metal to which a fiber body is mixed is arranged on at least one layer of each layer. Thus, satisfactory flexibility can be held without reducing the strength of the battery. |
