Abstract
To provide a piezoelectric ceramic containing BiFeOhaving a {110} plane orientation in a pseudo-cubic form, which is suited for the domain engineering, the piezoelectric ceramic includes a perovskite-type metal oxide represented by the following general formula (1), and has a {110} plane orientation in a pseudo-cubic form:BiFeO-(1−)ABO  General Formula (1)where A and B each represent one kind or more of metal ions; A represents a metal ion having a valence of 1, 2 or 3; and B represents a metal ion having a valence of 3, 4, or 5, provided that x is within a range of 0.3≦x≦1.
