Abstract
A filter element includes a piezoelectric layer with a polarization axis direction, and division resonators provided at the piezoelectric layer. Each of the division resonators includes a functional electrode on the piezoelectric layer. Each of the functional electrodes includes high and low potential electrodes. When a direction parallel or substantially parallel to a direction in which the high and low potential electrodes face each other and oriented from the high-potential electrode toward the low-potential electrode is an inter-electrode direction, and a number of division resonators having the forward direction relationship is equal to a number of division resonators having the opposite direction relationship.
