Liquid ejection head and method of manufacturing the same

A method of manufacturing a liquid ejection head, the method comprising:

• forming a conductive adhesive layer on a substrate having an energy-generating element to be used for ejecting a liquid arranged thereon;
• patterning the conductive adhesive layer and forming an electrode configured to generate a flow of the liquid and a wiring configured to supply electric power to the electrode, each of the electrode and the wiring comprising the conductive adhesive layer;
• and
• forming a flow path forming member, which has an ejection orifice for ejecting the liquid and is configured to form a flow path of the liquid between the flow path forming member and the substrate, on the substrate so that the flow path forming member is brought into contact with the wiring,
• wherein the flow path forming member contains an organic material, and
• wherein the conductive adhesive layer contains at least one of conductive diamond-like carbon or tin-doped indium oxide.
