ABSTRACT:
A surface acoustic wave device includes a piezoelectric substrate, at least one interdigital transducer (IDT) provided on the piezoelectric substrate, and a shield electrode provided on the piezoelectric substrate. The IDT has a first pattern on an edge that faces the shield electrode. The shield electrode has a second pattern on an edge so as to be evenly spaced apart from the first pattern.
