Patent ID: 7915791

Claim:
A quartz crystal device comprising: a container body having a recess; a pair of holding terminals formed on an inner bottom surface of the recess of the container body; and a crystal blank having a substantially rectangular shape and comprising a first principal surface, a second principal surface, a first end, a second end, a first side and a second side, the first principal surface being provided with a first excitation electrode with a first lead-out electrode extending from the first excitation electrode toward the first end at the first side of the crystal blank, and the second principal surface being provided with a second excitation electrode with a second lead-out electrode extending from the second excitation electrode toward the first end at the second side of the crystal blank; wherein the first and second sides of the first end of the crystal blank are fixed to the holding terminals using a conductive adhesive such that the crystal blank is held in the recess so as not to contact with pillow members unless a mechanical shock is applied, said pillow members being provided on an inner bottom surface of the recess of the container body at positions corresponding to corners of the first and second sides of the second end of the crystal blank, the two pillow members being independent of each other, wherein each of the excitation electrodes has a shape with portions corresponding to a corner at each of the first and second sides at the second end removed and a tip of the excitation electrode protrudes through a region between the two pillow members.
