Abstract
A surface mount type crystal oscillator is provided with a crystal blank, an IC chip which incorporates an oscillation circuit using the crystal blank, a substantially rectangular parallelepiped container body for surface mounting which houses the crystal blank and the IC chip, and mounting electrodes provided in four corners of an outer bottom surface of the container body. Each of the mounting electrodes is provided so as to extend over a side surface of the container body as an end face electrode. At least one adjustment terminal is disposed above the end face electrode on the side surface of the container body electrically isolated from the end face electrode. The adjustment terminal is longer along the height direction of the container body than the end face electrode.
