Abstract
A piezoelectric element, a piezoelectric vibrator and a manufacturing method thereof, and an electronic device, a piezoelectric structure is arranged on a first electrode, and a second electrode is arranged on the piezoelectric structure, wherein the second electrode includes a conductive layer and an anti-oxidation layer arranged on the piezoelectric structure in sequence. The conductive layer is configured to generate, when a breakdown short circuit occurs in the piezoelectric element, solid solution between a breakdown location of the piezoelectric element and anti-oxidation layer, and oxidize to generate an insulating material. The conductive layer and anti-oxidation layer are used as top electrodes of the piezoelectric element, when the breakdown short circuit occurs in the piezoelectric structure of the piezoelectric element, the conductive layer is melted by a huge amount of heat generated by the short circuit, a solid solution is formed by the anti-oxidation layer and the conductive layer.
