Liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• a channel substrate having
• one or more pressure chambers that constitute a channel for a liquid,
• at least one absorbing chamber that is coupled to the pressure chamber, constitutes the channel for the liquid together with the pressure chamber, and absorbs vibration of the liquid propagated from the pressure chamber, and
• a nozzle that is coupled to the pressure chamber and ejects the liquid;
• a vibration plate that is stacked on the channel substrate at a position overlapping the pressure chamber and at a position overlapping the absorbing chamber when viewed in a stacking direction;
• a first piezoelectric element that is provided on a first surface, which is one surface of the vibration plate on a side opposite to a side on which the pressure chamber is present, at a position overlapping the pressure chamber when viewed in the stacking direction and that vibrates the vibration plate to apply pressure to the liquid in the pressure chamber;
• a second piezoelectric element that is provided on the first surface of the vibration plate at a position overlapping the absorbing chamber when viewed in the stacking direction and that deforms to absorb at least some of the vibration of the liquid propagated from the pressure chamber;
• and
• a pressure detecting section that detects, based on an electromotive force of the second piezoelectric element, pressure of the liquid in the absorbing chamber.
