PROBLEM TO BE SOLVED: To provide a liquid ejection head simple in manufacturing and a recording apparatus using the same.SOLUTION: The liquid ejection head 2 includes: a planer rectangular flow channel member 4 having a liquid pressuring chamber surface facing a liquid ejection nozzle surface with a liquid ejection nozzle opened, a liquid pressuring chamber and the liquid ejection nozzle surface with the liquid introduction nozzle 5b of a manifold opened; a planar branch flow channel member 60 having a planer piezoelectric actuator 21 laminated on the liquid pressuring chamber surface, a signal transmission part, a recessed part 63 and a branch flow channel 61; and a reservoir flow channel member 40 having a reservoir flow channel 41, a penetration hole 42 and a side surface protection plate 43 and laminated on the branch flow channel member. The signal transfer unit is drawn out through the opening of the recess part and the through-hole onto the reservoir flow channel member, and the opening of the recess part is covered with the flow channel member and the side surface protection plate extending along the side surfaces including the long side of the branch flow channel member. |
