Piezoelectric ceramics, piezoelectric element, and electronic apparatus

A piezoelectric element comprising:

• electrodes;
• and
• at least one piezoelectric ceramics portion,
• wherein a piezoelectric ceramics forming the at least one piezoelectric ceramics portion comprises the piezoelectric ceramics comprising crystal grains each including:
• a first region formed of a perovskite-type metal oxide having a crystal structure in which a central element of a unit cell is located at an asymmetrical position;
• and
• a second region formed of a perovskite-type metal oxide having a crystal structure in which a central element of a unit cell is located at a symmetrical position, and is present inside the first region,
• wherein a ratio of a cross-sectional area of the second region to a cross-sectional area of the piezoelectric ceramics is 0.1% or less.
