Abstract
An ink jet recording head comprises a ceiling plate provided with a plurality of grooves to form ink paths, a plurality of extrusions confining the grooves, recesses serving as common liquid chambers conductively connected with the grooves, and supply apertures for supplying ink to the common liquid chambers; and an elemental substrate having a plurality of energy generating elements formed on it to generate energy for use of discharging ink. This ink jet recording head is formed by connecting such ceiling plate and elemental substrate, in which the ceiling plate is provided with a plurality of recesses, separation walls to separate adjacent common liquid chambers, and sealing material fill-in grooves formed on the separation walls, while the elemental substrate is provided with sealing material antirunning members for preventing the sealing material from flowing into each of the liquid chambers from the gaps between the separation walls and the elemental substrate, and then, the said sealing material is filled in the sealing material fill-in grooves. With the structure thus arranged, it is possible to fabricate the recording heads in good yield, while easily attaining the separation of common liquid chambers reliably.
