The present invention provides a piezoelectric material which does not use lead and potassium and which has a high piezoelectric constant and good insulating properties, and a piezoelectric element using the piezoelectric material. The piezoelectric material contains a perovskite metal oxide represented by the 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. The content of the auxiliary component according to the metal standard is 0.001 part by weight or more and 4.000 parts by weight or less based on 100 parts by weight of the perovskite type metal oxide. |
