Accumulator structure

An accumulator structure includes a module having a plurality of flat accumulators flatly disposed in a common plane, and the flat accumulators are electrically connected with each other via electrode terminals. Strip-shaped reinforcement members are attachedalternatelyat a front surface side and a back surface side of the module between the electrode terminals. Thereby, a reinforcement and insulation between the electrode terminals can effectively be carried out while a flat structure of the accumulator structure is maintained and bending flexibility is secured, and the accumulator structure can be adjusted to a third-dimensional installment shape.
