摘要： A surface acoustic wave device includes a surface acoustic wave resonator. The surface acoustic wave resonator includes comb-like electrodes (10) and reflection electrodes (22, 24) provided on both sides of the comb-like electrodes, and each of the reflection electrodes has at least two different pitches (λa1 to λan). It is thus possible to suppress the ripple components.
