<p>A piezoelectric resonator (10) capable of achieving a compact oscillator with high performance having high thermal resistance and a narrow tolerance is provided. A piezoelectric resonator (10) includes an element body (12) comprising an excitation layer (14) and a non-excitation layer (16). One vibration electrode (18, 20) is formed on the surface of the excitation layer (14) and another vibration electrode (18, 20) is formed between the excitation layer (14) and the non-excitation layer (16). The two vibration electrodes (18, 20) are formed from opposing ends of the excitation layer (14) toward the central portion thereof so as to oppose each other at the central portion of the excitation layer (14). On end-faces of the element body (12), end-face electrodes (22, 24) are formed so as to be connected to the vibration electrodes (18, 20), respectively.
