A sealed battery, which is one example of an embodiment of the present invention, comprises: an electrode body; a bottomed tubular outer housing can that accommodates the electrode body; and a sealing body that plugs an opening section of the outer housing can. The outer housing can or the sealing body has provided thereto an exhaust structure for discharging gas by breaking when internal pressure of the outer housing can exceeds a predetermined threshold. A sealed battery, which is one example of an embodiment of the present invention, comprises a potassium salt sheet that contains a potassium salt and that is disposed between an end surface of the electrode body and a bottom surface part of the outer housing can having the exhaust structure or the sealing body having the exhaust structure.
