    摘要: There is provided an apparatus that shows a much better transmission function characteristic in a signal passing band, and a low insertion loss. A plurality of pairs of electrode fingers constitute a first split electrode group of 5a1, 5b1, 5a2, 5b2, 5a3, 5b3, . . . . Further, a plurality of pairs of electrode fingers constitute a second split electrode group of 6a1, 6b1, 6a2, 6b2, 6a3, 6b3, . . . . The pairs of electrode fingers of both the groups are interleaved. The pairs of electrode fingers include electrode fingers of a width narrower than &lgr;/8 (&lgr; indicates the wavelength of a surface acoustic wave serving as the operation central frequency), and electrode fingers of a width wider than &lgr;/8, and the distance between the centers of the adjacent electrode fingers differs from &lgr;/4.

    摘要: An acoustic wave device includes a piezoelectric substrate, a resonator having comb electrodes that are provided above the piezoelectric substrate and excite an acoustic wave, and a capacitor that is provided above the piezoelectric substrate and is connected in series or parallel with the resonator, the capacitor including electrodes that horizontally face each other above the piezoelectric substrate. The electrodes of the capacitor are further from the piezoelectric substrate than the comb electrodes of the resonator.
