ABSTRACT:
A piezoelectric substance which is made of oxide with perovskite type structure which is made of ABO3, where a principal component of A is Pb, and principal components of B contain at least two kinds of elements among Nb, Mg, Zn, Sc, Cd, Ni, Mn, Co, Yb, In, and Fe, and Ti, characterized by being a uniaxial orientation crystal or a single crystal which has an a-domain and a c-domain of tetragonal.
