Abstract
To improve the frequency characteristics of an elastic wave filter. The elastic wave filter includes series resonators and parallel resonators as oblique resonators. In the series resonator, a duty of each of dummy electrode fingers is greater than a duty of each of electrode fingers in at least a part of a first intersection region where the electrode fingers intersect in the series resonator, and a duty at a base portion of each of the electrode fingers is greater than the duty of each of the electrode fingers in at least a part of the first intersection region. In the parallel resonator, the duty of each of the dummy electrode fingers is within a range of ±0.08 with respect to the duty of each of the electrode fingers in at least a part of a second intersection region where the electrode fingers intersect in the parallel resonator, and the duty at a base portion of each of the electrode fingers is within a range of ±0.08 with respect to the duty of each of the electrode fingers in at least a part of the second intersection region.
