PROBLEM TO BE SOLVED: To provide a piezoelectric device capable of reducing occurrence of short circuit across a first wiring and a second wiring due to a residue of a metal film formed on a piezoelectric body.SOLUTION: A piezoelectric device 1 includes: a piezoelectric body 4 formed on a substrate 2 having a plurality of sides； a first wiring 6 formed from the piezoelectric body 4 to the substrate 2； and a second wiring 7 formed from the piezoelectric body 4 to the substrate 2. Viewing from a thickness direction of the piezoelectric body 4, a second side 4b and a fourth side 4d, with which the piezoelectric body 4 and the first wiring 6 are overlapped, and a first side 4a and a third side 4c, with which the piezoelectric body 4 and the second wiring 7 are overlapped, are the sides different from each other.SELECTED DRAWING: Figure 1【課題】圧電体に設置された第１配線と第２配線とが金属膜の残渣により短絡することを低減できる圧電素子を提供する。【解決手段】圧電素子１は基板２上に設けられ複数の辺を有する圧電体４と、圧電体４から基板２にかけて設けられた第１配線６と、圧電体４から基板２にかけて設けられた第２配線７と、を備え、圧電体４の厚さ方向からみて、圧電体４と第１配線６とが重なる第２辺４ｂ、第４辺４ｄと、圧電体４と第２配線７とが重なる第１辺４ａ、第３辺４ｃと、が異なる辺になっている。【選択図】図１
