    摘要： An electrode foil includes a substrate made of metal and a rough layer disposed on a surface of the substrate and including plural fine metallic particles. The rough layer includes a lower layer, an intermediate layer which is disposed on the lower layer and is more distanced from the substrate than the lower layer is, and an upper layer which is disposed on the intermediate layer and is more distanced from the substrate than the intermediate layer is. The mode of diameters of fine particles in the intermediate layer is greater than the mode of diameters of the fine particles in the upper and lower layers. This electrode foil provides a capacitor having a small leakage current.

    摘要： An elastic wave element includes a piezoelectric substrate, an interdigital electrode provided on the piezoelectric substrate, a silicon oxide film covering the interdigital electrode, and a silicon nitride oxide film provided on the silicon oxide film. A film thickness H of the silicon oxide film and a wave length λ of an elastic wave propagating through the piezoelectric substrate satisfies a relation of H/λ≧0.15. The elastic wave element reduces fluctuation of propagation characteristics of elastic waves, and has high reliability.

    摘要： An acoustic wave device includes an interdigital transducer (IDT) electrode and a separate electrode facing the IDT electrode. The IDT electrode includes first and second comb-shaped electrode facing each other. The first comb-shaped electrode includes a first bus bar, first interdigitated electrode fingers, and first dummy electrode fingers. The second comb-shaped electrode includes a second bus bar second interdigitated electrode fingers interdigitated with the first interdigitated electrode fingers, second dummy electrode fingers facing the first interdigitated electrode fingers, weighted parts, and a non-weighted part. The weighted parts have electrodes at spaces between the second interdigitated electrode fingers and the second dummy electrode fingers. In the non-weighted part, there is no electrode at a space out of the spaces which is closest to the separate electrode in the non-interdigitated region. This acoustic wave device prevents short circuits between the IDT electrode and the separate electrode, and provides excellent characteristics of suppressing unwanted waves.

    摘要： An acoustic wave element includes a piezoelectric body, first and second interdigital transducer (IDT) electrodes provided on an upper surface of the piezoelectric body, and a first dielectric layer provided on the upper surface of the piezoelectric body to cover the first and second IDT electrodes. The first dielectric layer has a first part directly above the first IDT electrode and a second part directly above the second IDT electrode. The height of an upper surface of the second part of the first dielectric layer is larger than the height of an upper surface of the first part of the first dielectric layer. This acoustic wave element has a preferable temperature characteristic and electromechanical coupling factor.
