Low g-sensitivity crystal resonator

A crystal resonator being connected to a base via two conductive securing members, the crystal resonator, comprising:

• a crystal plate that is formed integrally, and that includes a first vibration section and a second vibration section connected to each other and arranged along an oscillating direction not parallel to a thickness direction, the crystal plate exhibiting a thickness shear mode, in which the crystal plate is driven to dynamically deform in the oscillating direction when applied with two applied voltages;
• and
• an electrode set that includes a first electrode pair disposed on the first vibration section, and a second electrode pair disposed on the second vibration section, the first electrode pair and the second electrode pair being configured to apply the applied voltages with opposite electrical polarities to the first vibration section and the second vibration section, respectively, which causes the first vibration section and the second vibration section to dynamically deform in the thickness shear mode along the oscillating direction;
• wherein in the thickness shear mode, the first vibration section and the second vibration section do out of phase motion with respect to each other;
• wherein:
• the first electrode pair includes an input node electrode and a back electrode that are disposed on two opposite surfaces of the first vibration section and that are aligned with each other with respect to the thickness direction;
