POSITIVE ELECTRODE FOR SECONDARY BATTERY AND SECONDARY BATTERY

A positive electrode for a secondary battery which is an example of the embodiment of the present invention comprises a collector, a protective layer formed on at least one surface of the collector, and a composite material layer formed on the protective layer. The protective layer has a first region and a second region. The first region includes inorganic particles and a conductive material. The second region includes inorganic particles and substantially does not include a conductive material, or includes inorganic particles and a conductive material, the content of the conductive material being less than the content of the conductive material in the first region.
