In a liquid ejection head comprising a plurality of opened liquid flow passages arranged side by side and communicating with ejection orifices through which a liquid is ejected, and thermal energy generating elements for generating thermal energy utilized to eject the liquid through the ejection orifices and generating bubbles in the liquid, at least one closed liquid flow passage closed at one end corresponding to the ejection orifice is provided in at least one end side of the plurality of opened liquid flow passages communicating with the ejection orifices. Since the closed liquid flow passage is not communicated with open air, the liquid is relatively hard to flow into the closed liquid flow passage. Accordingly, a bubble having the function of absorbing a liquid vibration caused upon ejection of the liquid is formed to extend from the interior of the closed liquid flow passage rearward. Vibrations of liquid meniscuses at the ejection orifices can be suppressed with the presence of the bubble. A method of manufacturing the liquid ejection head with ease is also provided.

An ink jet recording head comprises ink paths communicated with ink discharge ports for discharging ink, and heat generating portions arranged on the inner wall faces of the ink paths for generating thermal energy utilized for discharging ink from the discharge ports. For this ink jet recording head, liquid-repellent treatment is processed only on the regions that correspond to the heat generating portions of the inner wall faces of the ink paths. With the liquid-repellent treatment processed only on the regions corresponding to the heat generating portions on the inner wall faces of the ink paths, it is made difficult for the refractory substances that may be brought about by the decomposition of colorant or the like contained in ink to be fixed on the regions corresponding to the heat generating portions. As a result, the heat of each heat generating device is transferred to ink evenly to make stable ink discharges obtainable for the provision of recorded images in higher quality.
