摘要：
An ink jet head has a substrate on which ejection energy generating elements are provided, and a ceiling plate having a plurality of grooves for forming ink passages. The ceiling plate is pressed against the substrate by a pressing member, i.e., a spring. To improve the ejection performance of the ink jet head, the contact portion of the ceiling plate pressed by the pressing member is divided into a plurality of portions.
