PROBLEM TO BE SOLVED: To provide a polymer battery or capacitor, a manufacturing method of a polymer battery or capacitor and an inspection method for the same that is advantageous for grasping deterioration status. SOLUTION: This polymer battery or capacitor comprises a positive electrode 1, composed of positive electrode active material and polymer, a negative electrode 2 consisting of mainly negative electrode active material and polymer and a separating layer 3 separating the positive electrode and the negative electrode A marking for deterioration determination is provided at either one of the positive electrode 1, the separation layer 3 and the negative electrode 2. The marking for deterioration determination is formed of, for example, a convection pattern. |
