An ink jet head includes a passage-forming member providing a plurality of ink passages and an orifice plate having an array of ejection outlets in communication with respective ink passages. The orifice plate has a plurality of edge portions and the ejection outlets are arranged along a line that runs parallel to at least one of the edge portions and intersects opposing edge portions at crossing points. A confining member is configured to hold the orifice plate against the passage-forming member only in areas proximate to the crossing points.
