PURPOSE:To prevent that an adhesive may flow into an ink path to cause clogging or change in shape of the ink path by a method wherein the ink paths are formed by bonding a substrate with a top member with the recessed parts of the top member inside, and an adhesively tacking part is provided in an area other than the ink paths. CONSTITUTION:A heater board(substrate) 100 and a top plate (top member with recessed parts) 1300 are positioned to each other by abutting the end face of the heater board 100 against an orifice plate 400. An adhesive 1300c is applied to two adhesively tacking parts 1300a provided on the outer end part of the top plate 1300, and the both are bonded and tacked with each other so that liquid paths 1300d are corresponding to heat generation parts 100a of electrothermal conversion body. Because the tacking parts 1300a are provided in an area where the top plate 1300 is bonded to the heater board 100 but out of an area where the ink paths are formed, the adhesive 1300c can be prevented from flowing into the liquid paths 1300d as ink paths and a common liquid chamber 1300e.
