Abstract

An electrode according to one embodiment of the present disclosure comprises: a core material; and an electrode combined material that is layered onto surfaces of the core material. The electrode combined material comprises an active substance and PTFE. In an image illustrating a composition distribution obtained upon measuring a surface of the electrode combined material using energy dispersion-type X-ray analysis, the standard deviation of the area ratio of PTFE in 30 adjacent sections having a size of 150 μm×133 μm is 6% or less. When the electrode combined material is divided into three equal parts in the thickness direction to create, from the core material side, a first region, a second region, and a third region, the content (a) of PTFE in the first region, the content (b) of PTFE in the second region, and the content (c) of PTFE in the third region satisfy (c−a)/(a+b+c)≤±10%.
