Liquid Ejecting Head And Liquid Ejecting Apparatus

A liquid ejecting head comprising:

• a pressure chamber substrate in which wall surface portions of a pressure chamber in communication with a nozzle are formed;
• an diaphragm that is provided on a first surface side of the pressure chamber substrate in a laminating direction and forms a top surface portion of the pressure chamber;
• a piezoelectric element that is provided on the diaphragm;
• and
• a communication plate that is provided on a second surface side opposite to the first surface of the pressure chamber substrate in the laminating direction and forms a bottom surface portion of the pressure chamber, wherein
• a third surface of the communication plate is bonded to the second surface of the pressure chamber substrate by an adhesive and forms the bottom surface portion,
• the third surface is provided with a supply opening that supplies a liquid to the pressure chamber and a discharge opening that guides a liquid in the pressure chamber to the nozzle,
• the pressure chamber is longitudinal in a first direction when viewed in the laminating direction,
• at one end of the bottom surface portion in the first direction, a first acute angle portion is formed by the wall surface portions that mutually form an acute angle,
• at another end of the bottom surface portion in the first direction, a second acute angle portion is formed by the wall surface portions that mutually form an acute angle,
• the first acute angle portion does not overlap with the supply opening and the discharge opening when viewed in the laminating direction, and
• the second acute angle portion does not overlap with the supply opening and the discharge opening when viewed in the laminating direction.
