Abstract:
To manufacture a liquid ejection head, a film having a lower surface free energy than a surface free energy of a substrate is first formed on an inner face of a liquid supply port. Next, a dry film to be a flow path forming member is attached to cover the surface of the substrate, and then a member to be an ejection orifice forming member is provided on the surface of the dry film.

Claim (Index 1):
A method of manufacturing a liquid ejection head, the liquid ejection head including a substrate having formed a liquid supply port as a through-hole, an ejection orifice forming member having formed an ejection orifice configured to eject a liquid, and a flow path forming member for forming a flow path that communicates with the liquid supply port and the ejection orifice, on a surface of the substrate, the method comprising:\n a step of forming, on an inner face of the liquid supply port, a film having a lower surface free energy than a surface free energy of the substrate; a step of attaching a dry film to be the flow path forming member so as to cover the surface of the substrate having the liquid supply port provided with the film; and a step of providing, on an opposite face of the dry film to the face facing the surface of the substrate, a member to be the ejection orifice forming member.
