Abstract: A liquid ejection head includes a recording element substrate, a flow path member having a common supply flow path and a common collection flow path through which a liquid having a temperature higher than a temperature of the common supply flow path flows, and a support member supporting the flow path member. The common supply flow path and the common collection flow path are formed to extend along a longitudinal direction of the flow path member and be arranged side by side with each other in a lateral direction of the flow path member. The positions of the flow path member in the longitudinal direction and in the lateral direction are defined at a center portion in the longitudinal direction, and at a side surface located on the common supply flow path side in the lateral direction, among side surfaces extending in the longitudinal direction, respectively.

Abstract: A resin molding method includes a first molding step of molding a first molded part and a second molded part in a mold and a second molding step of joining the first molded part and the second molded part. In the first molding step, the second molded part is formed by injecting resin into an area where a first core movable in the first direction and a second core movable in a second direction are engaged. In the second molding step, the second molded part is joined to the first molded part by injecting the resin while the first core is in contact with the second molded part and the second core is removed from the second molded part. Areas where the first core and the second core are located in the first molding step become hollow areas connected to each other and part of ends of the first core in the first direction is not in contact with the second core.
