Abstract:
A liquid ejecting head includes a flow path forming substrate, a vibration plate that is formed on one surface side of the flow path forming substrate, a plurality of piezoelectric elements that are provided on the vibration plate, a protective substrate that is bonded to the one surface side of the flow path forming substrate and has a flow path, a flow path member that is bonded to a side of the protective substrate opposite to the flow path forming substrate, a drive circuit that is mounted in a space formed so as to be surrounded by the flow path forming substrate, the protective substrate, and the flow path member, a filler that is filled between the drive circuit and the protective substrate, and a protective film that is formed on an inner wall, in which the protective film has an exposure hole exposing a surface of the filler.

Claim (Index 1):
A liquid ejecting head comprising:\n a nozzle plate on which a first nozzle row including a first nozzle ejecting a liquid and a second nozzle row including a second nozzle ejecting a liquid are formed; a flow path forming substrate on which a first pressure generation chamber communicating with the first nozzle and a second pressure generation chamber communicating with the second nozzle are formed; a vibration plate that is formed on one surface side of the flow path forming substrate; a first piezoelectric element that is provided on the vibration plate at a position corresponding to the first pressure generation chamber; a second piezoelectric element that is provided on the vibration plate at a position corresponding to the second pressure generation chamber; a protective substrate that is bonded to the one surface side of the flow path forming substrate and has a flow path; a flow path member that is bonded to a side of the protective substrate opposite to the flow path forming substrate; a drive circuit that is mounted in a space formed so as to be surrounded by the flow path forming substrate, the protective substrate, and the flow path member, between the first piezoelectric element and the second piezoelectric element of the flow path forming substrate to drive the first piezoelectric element and the second piezoelectric element; a filler that is filled between the drive circuit and the flow path forming substrate, and between the drive circuit and the protective substrate; and a protective film that is formed from an inner wall of the flow path of the protective substrate to a boundary side with at least the inner wall of a bonding surface of the protective substrate with the flow path member, wherein the protective film has an exposure hole exposing at least a portion of a surface of the filler.
