There is provided an inkjet print head including: a substrate; a nozzle plate which forms a space where ink is to be filled between the substrate and the nozzle plate and on which plural orifices for ejecting ink are formed; and heaters which form bubbles to push ink droplets out through the orifices, wherein the heaters are installed on elevation parts elevated from the substrate and inserted into the orifices. According to such a structure, since the orifices for ejecting ink droplets, themselves, act as partition members against adjacent heaters, the structure can be greatly simplified. It becomes possible to control the ejection of ink droplets precisely because there is little possibility that reverse flow occurs when bubbles are expanded.
