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

Abstract

A liquid discharge recording head comprises an orifice plate having discharge port formed therefor to discharge liquid, and the main body portion having liquid flow paths formed therein to be communicated with the opening arranged at the edge portion thereof, the discharge port and the opening being bonded to communicate with each other. For this liquid discharge recording head, a sealing groove is arranged on the circumference of the opening along the bonded face, and filler is filled in the sealing groove, hence making 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 orifice plate so as to eliminate any gaps from which filler leaks between the orifice plate and the face having opening formed therefor, and carry out sealing by distributing filler over the entire area of sealing groove in an amount required for sealing appropriately without clogging the circumference of opening or discharge port.
