Abstract

See full text

An elastic wave device includes a resonator and an inductor. One end of the inductor is connected to the resonator, and the other end of the inductor is connected to a ground electrode or a signal electrode. The elastic wave device includes a chip and a mounting substrate. The chip includes a piezoelectric substrate and an interdigital transducer electrode provided on the piezoelectric substrate so define the resonator. The chip is mounted on the mounting substrate. The inductor is provided to the mounting substrate. A dummy electrode to which the one end side of the inductor is connected and the ground electrode or the signal electrode are provided on a surface of the mounting substrate that is opposite to the chip.
