摘要:
A liquid ejecting head includes: a passage forming board which is provided with pressure generating chambers respectively communicating with nozzle openings for ejecting a liquid; piezoelectric elements which are provided on one surface of the passage forming board to cause a pressure variation in the pressure generating chambers; terminals which are provided on the one surface of the passage forming board to be conductively connected to the piezoelectric elements and each have an inclined connection surface on a surface opposite to the passage forming board; and a wiring board which is electrically connected to the connection surfaces of the terminals and has a wiring layer supplying a driving signal for driving the piezoelectric elements. Each of the connection surfaces is higher on a side of the piezoelectric elements than on an opposite side of the piezoelectric elements with respect to a predetermined reference surface.
