Abstract
A quartz crystal device includes a crystal element, a container, a conductive adhesive having flexibility, first pillow portions, and a second pillow portion. The first pillow portions hold the crystal element floated from an inner bottom surface of the container at the proximities of the two positions. The second pillow portion opposes the crystal element at a proximity of a second side. The second side opposes the first side of the crystal element. A height of the first pillow portion is represented as h and a length of the first pillow portion in a direction perpendicular to the first side is represented as X, where the h is 20 μm to 50 μm and the Xis 150 μm or less. The conductive adhesive covers at least a top surface and a side surface of the first pillow portion. The side surface is in a center side of the crystal element.
