Abstract

An electrode is provided that includes a base (21), an electrode mixture layer (22) on the base (21), and an insulating layer (23) on the electrode mixture layer (22). In a surface image of the insulating layer (23), the insulating layer (23) includes unit insulating layers each surrounded by a non-insulating layer region where the insulating layer (23) is not formed. When a part of the unit insulating layers having a greatest number among unit layers having an area (µm<2>) of 1,000 µm<2> or more are designated as first insulating regions (23a), and another part of the unit insulating layers each having an area (µm<2>) two times or more of an area of each of the first insulating regions (23a) are designated as second insulating regions (23b), the insulating layer (23) includes both the first insulating regions (23a) and second insulating regions (23b).
