<P>PROBLEM TO BE SOLVED: To provide a liquid ejection head having good liquid sealability, in which a support member supporting an ejection device substrate and a liquid supply member for supplying a liquid to the ejection device substrate are connected with extremely good compatibility, even when the substrate narrowing technology is advanced. <P>SOLUTION: The liquid ejection head includes the ejection device substrate having a substrate provided with an energy-generating element, the liquid supply member that supplies the liquid to the ejection device substrate, and the support member that is provided between and connected to the ejection device substrate and the liquid supply member. The support member has at least two liquid supply flow paths that are through-holes extending through the support member and has a protrusion or recess at its connection surface with respect to the liquid supply member. A spacing between two adjoining liquid supply flow paths at the connection surface with respect to the liquid supply member is larger than a spacing between the adjoining two liquid supply flow paths at a connection surface of the support member with respect to the ejection device substrate. The support member is connected with the liquid supply member by integral molding. <P>COPYRIGHT: (C)2013,JPO&INPIT |
