Abstract:
A method for manufacturing a liquid ejecting head including a plurality of discharge ports through with liquid is discharged, a plurality of heat generating elements for applying thermal energy to said liquid, a plurality of liquid flow paths, each of said liquid flow paths communicating with a respective one of said discharge ports and including a bubble generating area where a bubble is generated by a respective one of said heat generating elements, and a separation wall having a plurality of movable members, each said movable member being displaceable above a respective one of said heat generating elements in accordance with generation of the bubble, said head discharging liquid by directing the pressure caused upon the generation of the bubble toward the respective discharge port by displacement of each said respective movable member, said method comprising the steps of:preparing a substrate provided with said plurality of heat generating elements; forming a grooved separation wall having said movable members formed in said grooved separation wall and partition portions for partitioning adjacent ones of said bubble generating areas; and joining said grooved separation wall and said substrate so as to form said plurality of bubble generating areas.
