Patent ID: 8087748

Claim:
An ink jet recording head comprising: a substrate provided with an energy-generating element for generating energy for discharging liquid; a discharge port provided corresponding to the energy-generating element; a flow path wall forming member which forms, in combination with the substrate, a path for supplying the discharge port with liquid, wherein the flow path wall forming member includes a cured substance of a photocurable resin composition containing: (a) a cationically polymerizable resin, (b) a cationic photopolymerization initiator, and (c) a condensate containing a tri-functional hydrolysable organosilane compound having an aromatic ring (tri-functional indicating a number of condensable groups present on one Si atom) and a hydrolysable organosilane compound without an aromatic ring, and wherein the hydrolysable organosilane compound without an aromatic ring has a group capable of a cationic polymerization.
