description The present invention is aimed to provide a piezoelectric compound having no occurrence of segregation or uneven structures as well as a piezoelectric element having excellent piezoelectric properties. The piezoelectric composition of the present invention is characterized in that a main component is a perovskite-typed oxide represented by formula of ABO 3 , wherein, A site comprises Bi, Na, and B site comprises Ti, and part of the Ti is substituted by transition metal element Me (Me is at least one element selected from the group consisting of Mn, Cr, Fe and Co), according to the conversion of BiMeO 3 , the content ratio of Bi and the transition metal element Me accounts for 6~43 mol% relative to the whole perovskite-typed oxides as the main component.
