    摘要: A thin-film capacitor that is less prone to generation of internal cracking or peeling is provided. In a thin-film capacitor according to the present embodiment, because through holes H are formed in internal electrodes containing Ni as a principal component in a lamination direction, a surface area of at least some of the through holes H is in the range of 0.19 μm2 to 7.0 μm2, and a ratio of a surface area of the through holes H to a surface area of an entire main surface of the internal electrodes is in the range of 0.05% to 5%, peeling or cracking is suppressed from occurring at the boundaries between the internal electrodes and dielectric layers, and as a result, the yield is enhanced.

    摘要: In a dielectric element, the side faces are roughened so that the surface roughness Ra is 15 nm or greater. By this means, the area of contact between a glass epoxy resin substrate and insulating material is increased, adhesion with resin substrates is improved, and strength and reliability can be enhanced when buried between two resin substrates. In the dielectric element, the surface roughness Ra of side surfaces is 5000 nm or less, so that when burying the dielectric element between a glass epoxy resin substrate and insulating material, the occurrence of air bubbles between the surface of the dielectric element and the resin can be prevented.
