A piezoelectric vibrator of the present invention has a base (1), an integrated circuit element (2), and a piezoelectric vibration element (3). The base (1) has external terminals that include an alternating current output terminal, and internal terminal pads. The base (1) is configured by laminating three or more rectangular ceramic substrate layers, each of which has castellation structures (C1-C4) formed at the four corners. Among the internal terminal pads, internal terminal pads (NT1, NT2) for the integrated circuit element, and the internal terminal pads (NT7, NT8) for the piezoelectric vibration element are connected to each other by means of wiring patterns (H9, H10) exposed to the outside, said wiring patterns being formed on the upper surfaces of the castellation structures (C3, C4) at the corners of the ceramic substrate of an intermediate layer. |
