A piezoelectric material that does not use lead and potassium and has a high piezoelectric constant and good insulating properties and a piezoelectric element that uses the piezoelectric material are provided. The piezoelectric material contains a perovskite-type metal oxide represented by general formula (1): (NaxBa1-y)(NbyTi1-y)O3 (1) (where 0.80≦x≦0.95 and 0.85≦y≦0.95), and an auxiliary component containing at least one selected from the group consisting of Si and B. A content of the auxiliary component on a metal basis is 0.001 parts by weight or more and 4.000 parts by weight or less relative to 100 parts by weight of the perovskite-type metal oxide.
