A piezoelectric composition containing: at least one or more elements selected from alkali metal elements; at least one or more elements selected from a group consisting of vanadium, niobium, and tantalum; copper or copper and germanium; and oxygen. The piezoelectric composition has a main phase, and a high Cu-concentration phase in which a content ratio of copper is higher than the main phase, and when a content ratio of oxygen in the high Cu-concentration phase is set as Og, and a content ratio of copper is set as Cug, Og and Cug satisfy relationships of 51≤Og≤60 and 2.0≤Cug≤15.
