To provide the piezoelectric device and the manufacturing method thereof, in which the quartz-crystal side surface electrodes and the base side surface electrodes are ensured to be electrically connected without disconnection. The piezoelectric device (100) comprises: a piezoelectric vibrating piece (21), an outer frame (22), a piezoelectric frame (20) for forming a first castellation (204), a package base (12) which is bonded by to the outer frame by adhesive (13) and which the second castellation is formed, and a package lid (11). The piezoelectric frame comprises: an excitation electrodes, a second extraction electrodes and a first side surface electrodes formed on the first castellation. The package base comprises: a second side surface electrode formed on the second castellation, and an external electrode. A pair of connection electrodes (14) is formed on the first castellation or second castellation, for electrically connecting the first side surface electrode or the first extraction electrode to the second side surface electrode. |
