摘要： A power supply-heater wiring and a heater-driving circuit wiring for a heater located on the right side of a supply port can be laid out utilizing a beam portion configured to separate supply ports from each other. Furthermore, a plurality of supply ports are provided to supply ink to channels and pressure chambers and separated from one another by beam portions. Thus, an ejection structure such as an ejection opening can be located on both sides of each of the supply ports. Even if the ejection structures are relatively densely arranged, the heaters and the like can have necessary and sufficient sizes and locations without being restricted by the arrangement. A wiring connecting the heater to the power supply wiring or driving circuit is also laid out on the beam portion serving as a partition wall for the supply ports.

摘要： An object of the present invention is to provide an ink jet print head configured to reduce the inclination of an ink ejection direction to make improper print conditions such as stripes and density unevenness unnoticeable. To achieve the object, an individual wire is extended to lie under a common wire. Thus, wires under ink channels arranged on the respective opposite sides of a pressure chamber 40 are made symmetric. Consequently, an equivalent step structure is provided at the bottoms of the ink channels arranged on the respective opposite sides of a pressure chamber 40.
