Abstract
A crystal vibration device where a crystal unit is supported on a case substrate in a cantilever manner by first and second conductive adhesive layers. The crystal unit has a length direction and is formed using a rectangular-plate-shaped crystal substrate and A>4.30t+0.16, where A (mm) represents a shorter distance among distances between a central axis of the crystal substrate and end portions of the first and second conductive adhesive layers on a central axis side, and t (μm) represents a thickness of the crystal substrate.
