A capacitor that comprises a capacitor element that includes an anode that contains a dielectric formed on a sintered porous body, a solid electrolyte overlying the anode, and a cathode coating is provided. The cathode coating includes a noble metal layer (e.g., gold) overlying the solid electrolyte and a layer overlying the noble metal layer that includes sintered metal particles (e.g., silver particles).

An electrolytic capacitor includes: an anode body having a dielectric layer; a solid electrolyte layer in contact with the dielectric layer; and an electrolytic solution. The electrolytic solution contains a solvent and a solute. The solvent contains a glycol compound. The solute contains a carboxylic acid component and a base component. A ratio of the carboxylic acid component in the solute is 200 parts by mass or more with respect to 100 parts by mass of the base component.

Conductive, elastic ionic polymers with high tensile strength (iono-elastomers) resulting from amphiphilic polymers capable of self-assembly into micellar hierarchical gel-like structures in an electrically conductive liquid are provided. The micellar hierarchical gel-like structures engage in micellar corona cross-linking to form the iono-elastomers. The iono-elastomer exhibits high stretchability and displays increased electrical conductivity upon mechanical stretching. A method for producing iono-elastomers includes mixing amphiphilic polymers in a conductive liquid to form micellar hierarchical gel-like structures, and cross-linking the micellar coronas. Devices incorporating iono-elastomers and methods for creating such devices are also provided. The devices incorporating the iono-elastomers may be wearable.

Provided is a laminate material capable of easily forming a metal exposed portion. The laminate material 1 is a laminate material formed by bonding and laminating a resin layer 17, 18 on at least one surface of a metal foil 11. A recess 27, 28 in which a foil thickness of the metal foil 11 is reduced is formed on a part of a bonding surface of the metal foil. A peeled portion 21, 22 where the resin layer 17, 18 corresponding to the recess 27, 28 has been peeled from the metal foil 11 is formed.
