Summary:PROBLEM TO BE SOLVED: To provide a surface acoustic wave device which efficiently suppresses unnecessary responses and causes low loss. SOLUTION: The surface acoustic wave device 1 includes: a pair of reflectors 2; and an interdigital transducer disposed between the pair of reflectors and has a crossed electrode 32 having a crossed part 321 and a dummy part 322 and a dummy electrode. A length of the dummy electrode and the length of the dummy part 322 of the crossed electrode adjacent to the dummy electrode are mutually different. COPYRIGHT: (C)2011,JPO&INPIT
