A surface acoustic wave device includes a first surface acoustic wave filter forming a ladder filter circuit; and a second surface acoustic wave filter having a passband at a frequency range higher than that of the first surface acoustic wave filter. The first surface acoustic wave filter includes a series-arm surface acoustic wave resonator, a parallel-arm surface acoustic wave resonator and an additional surface acoustic wave resonator. The series-arm surface acoustic wave resonator is on a series arm of the ladder filter circuit and includes an IDT electrode. The parallel-arm surface acoustic wave resonator is on a parallel arm of the ladder filter circuit and includes an IDT electrode. The additional surface acoustic wave resonator includes an IDT electrode, is connected in parallel with the series-arm surface acoustic wave resonator, and has a resonance frequency higher than the frequency range of the passband of the second surface acoustic wave filter.
