  • Elastic wave device
    Patent number: 10847707
    Abstract: An elastic wave device includes, when a region of a main surface of a piezoelectric substrate in which a first functional electrode including a comb-shaped or substantially comb-shaped electrode and reflectors and a second functional electrode including a comb-shaped or substantially comb-shaped electrode and reflectors are provided is referred to as a first region, and the remaining region of the main surface is referred to as a second region, first metal members provided in the second region so as to be adjacent to the first functional electrode and second metal members provided in the second region so as to be adjacent to the second functional electrode. The first and second metal members are not electrically connected to any of the functional electrodes. A dielectric film is provided on the main surface of the piezoelectric substrate so as to cover the functional electrodes and the first and second metal members.
    Type: Grant
