Liquid discharge recording head, method of manufacture therefor, and liquid discharge recording apparatus
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.
