Claim 5:
6. A liquid ejection head comprising:
a recording element substrate including an energy generating element configured to generate energy for ejecting liquid from an ejection port;
an electrical wiring board electrically connected to the recording element substrate to supply an electric signal for driving the energy generating element;
a first support member supporting the recording element substrate; and
a second support member supporting the first support member and having a greater linear expansion coefficient than that of the electrical wiring board, wherein
the electrical wiring board is bonded to a first surface of the first support member and a third surface of the second support member substantially orthogonal to the first surface, and
the second support member has a second surface that is an inclined surface between an edge of the first surface and an edge of the third surface that is substantially orthogonal to the first surface.
