  • Patent number: 11398354
    Abstract: A thin film capacitor is provided with a lower electrode made of a metal foil containing many metal grains, a dielectric thin film formed on an upper surface of the lower electrode, and an upper electrode formed on an upper surface of the dielectric thin film. A lower surface of the lower electrode is an etched surface from which cross sections of the metal grains appear. The height difference between the cross sections of adjacent metal grains in the etched surface is 1 ?m or more and 8 ?m or less.
