Abstract
To provide a quartz oscillator chip that can improve vibration characteristics. [Solution] The quartz crystal oscillator chip includes a housing and a quartz crystal oscillator. The quartz crystal oscillator is installed inside the housing. The quartz crystal oscillator includes a planar substrate, two electrodes, and two conductive silver pastes, the two electrodes being installed on two opposing main surfaces of the planar substrate. The planar substrate has at least one recess, which is located on the side of the planar substrate, perpendicular to the side, and recessed in a direction toward the interior of the planar substrate. The height of the recess is the same as the thickness of the planar substrate, and the two conductive silver pastes connect the planar substrate to the housing.
