Liquid ejecting head and liquid ejecting apparatus

A liquid ejecting head comprising:

• a nozzle substrate that is provided with a nozzle for ejecting a liquid;
• a pressure chamber substrate that includes
• a pressure chamber in which pressure for ejecting the liquid from the nozzle is applied to the liquid, and
• an absorption chamber that is adjacent to the pressure chamber in a second direction and absorbs vibration of the liquid generated when the pressure is applied to the liquid in the pressure chamber;
• a first vibration plate that is provided corresponding to the pressure chamber and vibrates to apply the pressure to the liquid;
• a second vibration plate that is provided corresponding to the absorption chamber and vibrates to absorb the pressure of the liquid;
• a wiring portion that is provided at a position corresponding to the absorption chamber;
• and
• a pressure acquisition portion that acquires the pressure of the absorption chamber based on a resistance value of the second wiring portion,
• wherein the
• wiring portion is configured to have a second bellows shape that is folded sequentially while extending along the second direction.

• a first wiring portion that is provided at a position that does not correspond to the absorption chamber;
• a second vibration plate that is provided corresponding to the absorption chamber and vibrates to absorb the pressure of the liquid;
• a second wiring portion that is provided at a position corresponding to the absorption chamber;
• and
• a pressure acquisition portion that acquires the pressure of the absorption chamber based on a resistance value of the second wiring portion, wherein
• when viewed in an up-down direction intersecting the first direction and the second direction,
• the second wiring portion is provided at a position overlapping the absorption chamber,
• the first wiring portion is provided at a position that does not overlap the pressure chamber and the absorption chamber, and
• the first wiring portion is provided at a position between the pressure chamber and the absorption chamber in the second direction.
