摘要： A SAW device has an IDT which is provided in the principal surface of a quartz crystal substrate having Euler angles (−1.5°≦φ≦1.5°, 117°≦θ≦142°, |ψ|≠90°×n (where n=0, 1, 2, 3)) and excites a Rayleigh wave (wavelength: λ) in a stopband upper end mode. Inter-electrode-finger grooves are recessed between the electrode fingers of the IDT. The depth G of the inter-electrode-finger grooves is 0.01λ≦G≦0.07λ, and an electrode finger thickness H and an IDT line occupancy η satisfy a predetermined relationship. Thus, a frequency-temperature characteristic constantly has an inflection point between a maximum value and a minimum value in an operation temperature range, thereby suppressing a fluctuation in an inflection-point temperature due to a manufacturing variation in the IDT line occupancy η.

The inflection point is adjustable to a desired temperature or a desired temperature range depending on the IDT line occupancy η within an operation temperature range.
