ABSTRACT:
A contour resonator at least includes a first vibrating substrate and a second vibrating substrate having main surfaces that face each other and are bonded. The contour resonator includes a first excitation electrode provided on a front main surface of the first vibrating substrate, a second excitation electrode provided on a back main surface of the second vibrating substrate, and a common intermediate excitation electrode provided at an interface between the first vibrating substrate and the second vibrating substrate. The first excitation electrode and the second excitation electrode are electrically connected to constitute a first terminal. The intermediate excitation electrode constitutes a second terminal. The first vibrating substrate and the second vibrating substrate perform a contour vibration in accordance with an excitation signal applied between the first terminal and the second terminal.
