Patent ID: 8393717

Claim:
A liquid ejecting head capable of ejecting a liquid from pressure generating chambers through nozzles by varying pressure of the pressure generating chambers by pressure generating units, the liquid ejecting head comprising: a nozzle plate in which the nozzles are formed and which is formed of an insulating material; a first passage forming board to which the nozzle plate is joined and in which a first liquid passage including the pressure generating chambers is formed and which is formed of an insulating material; a vibration plate which is disposed on the first passage forming board and forms one surface of the first liquid passage; and a second passage forming board which is joined to the surface of the first liquid passage forming board close to the vibration plate and has a second liquid passage communicating with the first liquid passage, wherein a first electrode layer electrically connected to the liquid in the first liquid passage and a second electrode layer independent from the first electrode layer are disposed on the vibration plate, and wherein the first and second electrode layers each include a terminal drawn to the outside of a junction portion joining the first and second passage forming boards to each other.
