    • An ink jet recording head can record an image having a high quality level for a long period of time by use of a material having a reduced linear expansion coefficient and a satisfactory patterning characteristic. The liquid discharge head includes an energy generating element which generates energy for discharging a liquid; a discharge port which discharges the liquid; and a flow path forming member to form a flow path which supplies the liquid to the discharge port, the flow path forming member being formed of a cured material of a resin composition including a cationic polymerizable resin, a cationic photopolymerization initiator, a condensation product of hydrolyzable organic silane compounds, and inorganic fine particles having an average particle diameter of 50 nm or less.
