Original Abstract Submitted
a liquid ejecting head includes a piezoelectric element, a diaphragm, a reinforcing film, and a pressure chamber substrate. the reinforcing film is formed along a first direction, overlaps a boundary between the partition wall and the pressure chamber, and satisfies y1>y2 and 0<a1<a2 where y1 is a first thickness of the reinforcing film in the lamination direction at a first position, y2 is a second thickness of the reinforcing film in the lamination direction at a second position closer to the center of the pressure chamber than the first position, a1 is an absolute value of a slope of a first tangent line, to an inclined surface as a surface of the reinforcing film that is not in contact with the diaphragm, at the first position, and a2 is an absolute value of a slope of a second tangent line at the second position.
