ABSTRACT:
To make a substantial mounting area smaller. A piezoelectric resonator has a piezoelectric resonator element accommodated in a package. The piezoelectric resonator element includes a pair of connection electrodes which are connected to excitation electrodes. The respective connection electrodes are joined to mount electrodes formed in the package. The piezoelectric resonator includes four external electrodes at the outer surface of the bottom of the package. The external electrodes disposed along the shorter latus of the package on one side in the lengthwise direction thereof are electrically connected with the mount electrodes to which the respective connection electrodes of the piezoelectric resonator element are connected.
