ABSTRACT:
In a surface acoustic wave device, electrode films constituting at least one IDT are disposed on a piezoelectric substrate, and an SiO2film is arranged on the piezoelectric substrate so as to cover the electrode films. The film-thickness of the electrode films is in the range of about 1% to about 3% of the wavelength of an excited surface acoustic wave.
