Abstract

A liquid ejecting head includes: a substrate; a first electrode; a piezoelectric layer covering the first electrode; a second electrode positioned on the piezoelectric layer; a plurality of pressure chambers arrayed in a first direction; and a rigid layer. Each pressure chamber has one end portion and another end portion in a second direction. The rigid layer has an edge providing a plurality of convex parts and a plurality of concave parts. Each convex part and each concave part are alternately arrayed with each other in the first direction. Each convex part is positioned outside each pressure chamber and protrudes in the second direction toward the another end portion. Each concave part is positioned at each pressure chamber and is concaved in the second direction away from the another end portion.
