摘要：A surface acoustic wave (SAW) resonator and a SAW oscillator and an electronicapparatus including the resonator are to be provided. A SAW resonator includes: an IDTexciting a SAW using a quartz crystal substrate of Euler angles (−1.5°≦φ≦1.5°,
117°≦θ≦142°, 42.79°≦|ψ|≦49.57°); one pair of reflection units arranged so as allow the IDTto be disposed therebetween; and grooves acquired by depressing the quartz crystalsubstrate located between electrode fingers. When a wavelength of the SAW is λ, and adepth of the grooves is G, “0.01λ≦G” is satisfied.
