1. An electrode comprising:
a conductive composition containing:
a conductive polymer;
a binder resin; and
a plasticizing agent,
wherein
the electrode has a plate shape, with the plate shape having a pair of principal surfaces parallel to each other,
the conductive polymer is PEDOT/PSS,
the binder resin is a water-soluble polymer,
a content of the conductive polymer is 0.20 to 12 parts by mass with respect to 100 parts by mass of the conductive composition,
a ratio of a content of the plasticizing agent to a content of the conductive polymer in a surface part of the electrode located at less than or equal to 1 μm from at least one principal surface of the pair of the principal surfaces of the electrode is greater than a ratio of a content of the plasticizing agent to a content of the conductive polymer in an entirety of the conductive composition, and
the ratio of the content of the plasticizing agent to the content of the conductive polymer is 0.5 to 350.0 in the surface part of the electrode.
