    摘要： A liquid discharge recording head includes an orifice plate having a discharge port formed therefor to discharge liquid, and a main body portion having liquid flow paths formed therein to communicate with an opening arranged at an edge portion thereof, the discharge port and the opening being bonded to communicate with each other. A sealing groove is arranged on the circumference of the opening along the bonded face, and a filler is filled in the sealing groove. This makes it possible to pour filler into the sealing groove from the injecting groove after the orifice plate is bonded to the face having the opening formed therefor to communicate the opening with the discharge port of the orifice plate to eliminate any gaps from which the filler leaks between the orifice plate and the face having an opening formed therefor, and carry out sealing without clogging the circumference of opening or discharge port.

    摘要： The present invention provides a liquid ejection head for which the peeling of an orifice plate from a substrate seldom occurs, even in a structure such that the walls that define each energy application chamber are narrowed toward a ejection port. The walls that define a first pressure chamber are inclined inward within the first pressure chamber, so that the first pressure chamber is narrowed, toward an ejection port, along a direction perpendicular to the heater formation face on which heaters are arranged. Further, the walls that define each ink flow path are inclined in the ink ejection direction. Furthermore, the angle at which the walls that define the ink flow path are inclined relative to the ink ejection direction is smaller than the angle at which the walls that define the first pressure chamber are inclined inward, within the first pressure chamber.
