    Abstract: An electrolytic capacitor includes an anode body, a first conductive polymer layer, and a second conductive polymer layer. The anode body includes a dielectric layer. The first conductive polymer layer covers at least a part of the dielectric layer. The second conductive polymer layer covers at least a part of the first conductive polymer layer. The first conductive polymer layer includes a first conductive polymer. The second conductive polymer layer includes a second conductive polymer. At least one of the first conductive polymer layer and the second conductive polymer layer further includes a hydroxy compound. The hydroxy compound has two or more alcoholic hydroxy groups or two or more phenolic hydroxy groups, and has a melting point ranging from 40° C. to 150° C., inclusive.

    Abstract: A positive electrode for a secondary battery including a positive electrode current collector, and a positive electrode mixture layer containing a positive electrode active material and disposed on a surface of the positive electrode current collector. The positive electrode mixture layer contains a first positive electrode active material having a compressive strength of 400 MPa or more, and a second positive electrode active material having a compressive strength of 250 MPa or less. When the positive electrode mixture layer is divided into a first region and a second region having the same thickness, the first positive electrode active material is contained more in the first region than in the second region, and the second positive electrode active material is contained more in the second region than in the first region.
