摘要： An inkjet printer head includes a substrate having an ink-feed hole to supply ink stored in a cartridge to an ink chamber and a restrictor in fluid communication with the ink chamber, an oxide layer formed on the substrate, a heater disposed on the oxide layer above the restrictor and having fixed parts disposed on the oxide layer, slopes extending upward and away from the restrictor at an incline, and a parallel part extending between the slopes parallel to the substrate, a lead formed to be in electrical contact with the heater, a chamber layer formed to cover the lead and to define the ink chamber, and a nozzle layer formed on the chamber layer and having a nozzle. In the inkjet printer head, the lifespan of the heater may be extended since the heater is supported by the slopes, which function as a shock absorbing member when ink supply pressure or cavitation force is applied to a surface of the heater. In addition, since the heater does not have a right angle structure, the heater may be formed to have a uniform thickness even when a thin layer used for the heater is formed by a deposition method.
