In the disclosed piezoelectric devices a piezoelectric frame includes a vibrating piece. An excitation electrode is formed on the vibrating piece. An outer frame portion surrounds the vibrating piece and includes an extraction electrode connected to the excitation electrode. A package base is bonded to one surface of the outer frame portion and includes a connection electrode connected to the extraction electrode. The package base includes an external terminal formed on a surface thereof opposite the surface on which the connection electrodes are formed. Through-hole conductors connected the connection electrodes with respective external terminals. A lid is bonded to an opposing surface of the piezoelectric frame. An exhaust channel is in communication with the extraction electrode adjacent the through-hole conductors.
