摘要：
An ink jet head includes a first member (802) provided with an ejection energy generating element (807) for generating energy contributable to ejection of ink; a second member (801) provided with a recess (806) for defining a ink passage by being coupled with the first member, corresponding to the ejection energy generating element; a third member (803) provided with an ejection outlet (805) which communicates with the ink passage and through which the ink is ejected; wherein the ink passage has a trapezoidal cross-section.
