ELECTRODE FOR SECONDARY BATTERY, SECONDARY BATTERY PROVIDED WITH SAME, AND METHOD FOR MANUFACTURING ELECTRODE FOR SECONDARY BATTERY

The present disclosure provides an electrode for a secondary battery capable of measuring the width of a first mixture layer and the width of a second mixture layer when the first mixture layer and the second mixture layer are stacked and formed on the surface of a metal foil. A positive electrode body (electrode for a secondary battery) includes a strip-like positive electrode foil and a positive electrode mixture layer provided on the positive electrode foil. The positive electrode mixture layer includes a first positive electrode mixture layer provided on the positive electrode foil and a second positive electrode mixture layer provided on the first positive electrode mixture layer. The first positive electrode mixture layer has a width greater than a width of the second positive electrode mixture layer.
