摘要：A SAW resonator which, using a quartz crystal substrate with Euler angles(−1.5°≦φ≦1.5°, 117°≦θ≦142°, and 41.9°≦|ψ|≦49.57°), includes an IDT that excites a stop
band upper end mode SAW, and an inter-electrode finger groove provided betweenelectrode fingers configuring the IDT. When a wavelength of the SAW is λ, a first depth ofthe inter-electrode finger groove is G, a line occupation rate of the IDT is η, and anelectrode film thickness of the IDT is H, λ, G, η and H satisfy the relationship of 0
