| description | A vibration device includes a quartz substrate including a first vibration section, a second vibration section, and a third vibration section, a pair of first excitation electrodes formed at two principal surfaces of the quartz substrate, a pair of second excitation electrodes so formed as to sandwich the second vibration section in the thickness direction of the quartz substrate, and a pair of third excitation electrodes so formed as to sandwich the third vibration section in the thickness direction of the quartz substrate. At least one of the pair of second excitation electrodes is formed at a first inclining surface that inclines with respect to the two principal surfaces. At least one of the pair of third excitation electrodes is formed at a second inclining surface that inclines with respect to the two principal surfaces. The second inclining surface inclines with respect to the first inclining surface. |
