There is provided a configuration in which a lead-out electrode that extends out from an excitation electrode provided on a lower surface of a crystal piece facing an inner bottom surface of a container main body, is connected to a crystal terminal of an IC chip via a conducting path provided on the inner bottom surface of the container main body, and the conducting path is superimposed, in plan view, on the excitation electrode of the lower surface of the crystal piece, and the excitation electrode of the lower surface and the conducting path have the same electric potential, to thereby suppress the occurrence of stray capacity therebetween. As a result, stray capacity occurring in the conducting path that connects the excitation electrode and the IC terminal is made small, thereby preventing variations in oscillating frequency. |
