Abstract
An object is to provide a crystal device in which an influence due to an electroconductive adhesive is reduced, and vibration characteristics of a crystal piece are favorably maintained. A configuration is such that in a crystal device including: a container main body having a concavity, with a crystal retention terminal formed in a bottom face of the concavity, and with a mounting terminal that is electrically connected to the crystal retention terminal formed on an outer bottom face; a crystal piece accommodated in the concavity, with an excitation electrode formed on both main faces, and with a support electrode that is electrically connected to the excitation electrode using a connecting electrode, formed on both sides of one end portion, and with the support electrode bonded to the crystal retention terminal with an electroconductive adhesive; and a cover that is connected to an open end face of the container main body and hermetically seals the crystal piece, there is provided a jetty being a main face of the crystal piece, and that protrudes on a periphery of the support electrode, and the jetty is formed integral with the crystal piece.
