Abstract
A surface acoustic wave filter which includes a first terminal at the input side, a second terminal at the output side, a plurality of resonators electrically connected between the first and the second terminals, and a piezoelectric substrate provided on the upper surfaces of first and second terminals and the plurality of resonators. The piezoelectric substrate is made to have a thickness that is not thicker than 0.2 mm. The filtering characteristic of surface acoustic wave filter can be improved by taking advantage of the above structure.
