Abstract

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.

Description

technical field [0001] The present invention relates to a surface-mounted piezoelectric oscillator (hereinafter simply referred to as a piezoelectric oscillator). The surface-mounted piezoelectric oscillator uses a base and a cover to form a package, and a housing portion of the base accommodates a In the piezoelectric vibrating element and the integrated circuit element, an opening is formed on the upper surface of the substrate and a housing portion is formed inside, and the lid seals the opening. The present invention particularly relates to improving the package structure of the piezoelectric oscillator. Background technique [0002] A piezoelectric oscillator using a piezoelectric vibrating element such as a crystal vibrating plate can stably obtain a high-precision oscillation frequency. Therefore, the piezoelectric oscillator described above is used in various fields as a reference frequency source for electronic equipment and the like. In such a piezoelectric oscill...
