摘要： An inkjet print head with a high efficiency heater includes a substrate having an ink-feed hole extending therethrough to receive ink stored in a cartridge, a flow path layer to define an ink chamber in fluid communication with the ink-feed hole, a nozzle plate having a nozzle to discharge the ink from the ink chamber to an exterior, a heater located adjacent to an inner wall of the ink chamber and disposed in contact with the ink in the ink chamber, and a lead electrically connected to the heater. The heater increases thermal efficiency and maintains a stable structure. In addition, since the heater is disposed adjacent to the inner wall of the ink chamber, the heater is barely affected by the ink supply pressure or the cavitation force that results from ink bubbles shrinking.
