摘要： An inkjet printer head includes a substrate, an insulating layer having a groove and disposed on the substrate, a heating member having a concavely curved upper surface and disposed on an upper portion of the groove, an electrode to make contact with the heating member to apply electric current to the heating member, a chamber layer disposed on the heating member, and a nozzle layer having one or more nozzles and disposed on the chamber layer. According to the inkjet printer head, the heating member has a curved structure to increase a length of the heating member, so that resistance of the heating member can be increased. Thus, the heating member can stably operate regardless of current variation applied thereto, and the printing work can be performed.
