摘要：
A liquid ejecting apparatus includes: a piezoelectric element equipped with a piezoelectric layer contained a barium titanate-based complex oxide and electrodes that are provided in the piezoelectric layer; a temperature detection unit that detects temperatures; and a polarization unit that supplies a repolarization waveform to repolarize the piezoelectric layer to the piezoelectric element in the case where the temperature detection unit detects a predetermined temperature condition.
