Provided are a thin battery electrode group having high capacity and high flexibility, a thin battery including such an electrode group, and an electronic device incorporating the thin battery. The thin-film battery electrode group is interposed between the sheet-like first electrode, the sheet-like second electrode laminated on both surfaces of the first electrode, and the first electrode and the second electrode. And an electrolyte layer. The second electrode is different in polarity from the first electrode. Further, the flexural modulus of the second electrode is lower than the flexural modulus of the first electrode. The thin battery includes a thin battery electrode group and a bag-shaped exterior body that houses the electrode group. The electronic device includes a flexible electronic device main body, and a thin battery is built in the electronic device main body. |
