Abstract
The quartz crystal device includes a container body having: a recess; a pair of holding terminals formed on an inner bottom surface of the recess; and a crystal blank, both principal surfaces of which are provided with excitation electrodes with lead-out electrodes extending from the pair of excitation electrodes toward both sides of one end of the crystal blank. Both sides of one end of the crystal blank are fixed to the holding terminals using a conductive adhesive. Pillow members are provided on the inner bottom surface of the recess at positions corresponding to corners on both sides of the other end of the crystal blank, and the two pillow members are independent of each other. Alternatively, each holding terminal includes a first region formed near the facing holding terminal and a second region having a greater thickness than the first region formed far from the facing holding terminal.
