PROBLEM TO BE SOLVED: To provide an electrode which is excellent in elasticity and can maintain conductivity. An electrode 10 according to the present invention is a plate-shaped electrode containing a conductive polymer, a binder resin, and a plasticizer, and having a pair of main surfaces 11 and 12 parallel to each other. The ratio of the content of the plasticizer to the content of the conductive polymer in the surface layer portion having a depth of 1 μm or less from the surface of 10 is 0.5 to 500.0.
