PIEZOELECTRIC CERAMIC, MANUFACTURING METHOD THEREFOR, AND ELECTRONIC COMPONENT
A piezoelectric ceramic may be slightly deformed by firing, and a manufacturing method therefor, and an electronic component are disclosed. There is provided a piezoelectric ceramic including a plurality of crystal grains including a lead zirconate titanate-type crystal containing Zn, and Bi, and crystal grain boundaries existing between a plurality of the crystal grains, wherein a plurality of the crystal grains include first crystal grains, and wherein the first crystal grains have a content of at least one element of Zn and Bi present in the inside of the first crystal grains that is smaller than the content of the at least one element present in an area including the crystal grain boundaries that are in contact with the crystal grains. The piezoelectric ceramic is slightly deformed by firing and is capable of forming an electronic component which has little warp or deformation even if it is thin.
