Abstract

The present invention aims to provide an excellent piezoelectric composition and an excellent piezoelectric element if the piezoelectric properties especially a high spontaneous polarization and a sufficiently high resistivity, the low pollution, the environment and the ecology are considered. In the piezoelectric composition, the main component contains the substance represented by the following formula with a perovskite-typed structure, (BiNa)(TiMgAl)O. Wherein, 0.01≦x≦0.8, 0.2≦y≦0.8, 0.01≦z≦0.6, 0.75≦m≦1.0, and x+y+z=1.
