Abstract
A battery capable of inhibiting swollenness of the battery is provided. A cathode and an anode are layered with a separator and an electrolyte layer in between. The anode contains an anode active material containing Sn or Si as an element. The electrolyte layer contains an electrolytic solution and a high molecular weight compound. It is preferable that the distance between the cathode and the anode is from 15 μm to 50 μm, and the distance between the cathode and the separator and the distance between the anode and the separator are respectively from 3 μm to 20 μm. Thereby, expansion of the anode is absorbed, stress on the anode is reduced, and occurrence of wrinkles in the anode is inhibited.
