摘要： A liquid ejecting head that includes a fluid channel formation substrate and pressure generation units. The fluid channel formation substrate is made of a silicon single crystal substrate having a crystal face orientation of. The fluid channel formation substrate has a plurality of separate flow channels that include at least pressure generation chambers demarcated by partition walls, each of the pressure generation chambers being in communication with a nozzle opening that ejects liquid drops. The fluid channel formation substrate further has a communication portion that is in communication with each of the separate flow channels. The pressure generation units are provided so as to correspond to the pressure generation chambers and generate a pressure change in the pressure generation chambers so as to cause ejection of liquid drops.

摘要： A liquid ejection head including: a flow-channel forming substrate having a pressure generating chamber which communicates with a liquid supply channel which communicates with one end of the pressure generating chamber in terms of a first direction so as to have a first length for supplying liquid to the pressure generating chamber; and a pressure generating unit that causes the change in pressure in the pressure generating chamber, wherein the liquid supply channel is formed by narrowing the width of the pressure generating chamber in a second direction substantially perpendicular to the first direction so as to have a second length shorter than the first length, a stepped surface is formed between the side surface of the pressure generating chamber in the second direction and the side surface of the liquid supply channel in the second direction, and wherein a bridge is provided at a corner defined by the stepped surface, the side surface of the pressure generating chamber in the second direction on the stepped surface side, and one of the surfaces of the pressure generating chamber in a third direction which is orthogonal to the first direction and the second direction of the flow-channel forming substrate for bridging the corner.
