To provide a piezoelectric resonance part with high accuracy and strength which requires no assembling process and is capable of being miniaturized.

A part main body 22 consists of an integrally baked laminate including plural laminated ceramic layers, where a piezoelectric vibrator 25 is placed at an intermediate section of the layered product in its laminating direction with both ends of the vibrator 25 functioning as cases in the laminating direction. Furthermore, via hole connecting parts 34 and 35 are prepared to secure electrical connection at least between exciting internal electrodes 23, 24 which are used for the vibrator 25 and input/output terminal electrodes 31 and 32 formed on the outer surface of the main body 22 respectively.
