Abstract
A crystal device for surface mounting is provided with at least: a container body having a substantially rectangular outer shape and mounting electrodes formed in the four corners of the outside bottom surface of the container body; and a crystal blank hermetically sealed within the container body. The spacing of mounting electrodes on at least one side of the outside bottom surface is less than the length of the mounting electrodes in the direction along that side. A jetty having a height greater than the thickness of the mounting electrodes is provided in the cross-shaped area interposed between the mounting electrodes on the outside bottom surface.
