1. A liquid ejection head comprising:
a module equipped with a substrate capable of ejecting a liquid by driving an ejection energy generation element and a flow path part that is fluidly connected to the substrate;
a support member configured to support the substrate; and
a frame configured to support the module and the support member, the frame supporting the support member at an insertion surface of the module that is inserted and engaged,
wherein, if the module is inserted and engaged with the frame, the frame and the flow path part face each other via a space in a direction intersecting an inserting direction of the module and abut on each other in the inserting direction so as to be supported, and
wherein the frame comprises an opening penetrating in the inserting direction, an area of the opening located upstream with respect to the inserting direction being larger than an area of the opening located downstream with respect to the inserting direction.
