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.
