An electroacoustic component includes a substrate that includes a quartz single crystal. The quartz single crystal has a first Euler angle λ: −5°≦λ≦5°, a second Euler angle μ, and a third Euler angle θ. A contiguous region of the quartz single crystal has the following vertices P i (μ i , θ i ): (23°, 20°), (60°, 17°), (110°, 30°), (105°, 42°), (60°, 30°), (23°, 25°). |
