    摘要: A surface acoustic wave device includes a piezoelectric element, an IDT electrode formed on the piezoelectric element for exciting a principal wave, a reflection film formed on the piezoelectric element having a higher reflectivity than the reflectivity of the piezoelectric element in a visible light wavelength region, and a light permeable dielectric layer formed on the piezoelectric element, at least a part of the IDT electrode, and the reflection film. Accordingly, when measuring the film thickness of the light permeable dielectric layer by light interference method, the reflected light from the reflection film having a higher reflectivity than the reflectivity of the piezoelectric element in a visible light wavelength region can be utilized, so that the film thickness can be measured more accurately.

    摘要: An elastic wave device includes a piezoelectric substrate, an IDT electrode disposed on a piezoelectric device, a first dielectric layer disposed on the piezoelectric substrate such that it covers the IDT electrode, and a second dielectric layer disposed over the first dielectric layer. The second dielectric layer propagates transverse waves faster than that on the first dielectric layer. When a film thickness of the second dielectric layer is greater than a wave length of a major wave excited by the IDT electrode, a cut angle of the piezoelectric substrate in indication of Euler angles (φ, θ, Φ) is set to φ≠0°, θ≠0°, and Φ≠0°. This suppresses deterioration of device characteristics.
