Liquid discharge head and producing method therefor

A liquid discharge head comprising:

• an orifice plate having plural discharge openings for discharging liquid droplets;
• and
• a head main body provided with plural liquid paths for respectively communicating with said plural discharge openings, a liquid chamber for liquid supply to said plural liquid paths, a supply aperture for liquid supply to said liquid chamber, and plural energy generating elements provided corresponding to said plural liquid paths and adapted to generate energy for discharging the liquid droplet,
• said liquid discharge head being formed by adjoining said orifice plate with an adhesion face of said head main body on which are formed apertures of said liquid paths for communicating with said discharge openings of said orifice plate,
• wherein said orifice plate comprises a protruding portion on an adhesion face of said orifice plate, said protruding portion has a shape corresponding to a cross-sectional shape of one of said liquid paths and is provided with one of said discharge openings therein, said protruding portion or a part thereof is made to enter and to fit with one of said liquid paths of said head main body, and said adhesion face of said orifice plate is adjoined with said adhesion face of said head main body,
• and wherein said head main body is constituted by adjoining an element substrate and a ceiling substrate, said ceiling substrate being provided with said supply aperture for liquid supply to said liquid chamber, and said element substrate being provided with plural liquid path walls for forming said plural liquid paths upon adjoining with said ceiling substrate and being provided with said plural energy generating elements provided between respective pairs of said liquid path walls.
