摘要：
A liquid discharge recording head which discharges a liquid includes a substrate on which liquid-discharge-energy-generating elements are provided and which constitutes a part of a flow path for supplying the liquid; and a covering resin layer which is provided on the substrate, which constitutes a part of the flow path, and which includes orifices for discharging the liquid, wherein the covering resin layer is composed of an oxetane resin composition containing an oxetane compound having at least one oxetanyl group in its molecule and a photocationic polymerization initiator as essential components.
