A liquid discharge head includes a substrate including energy-generating elements that generate energy used to discharge a liquid, discharge ports through which the liquid is discharged, and a channel-forming member having a channel in which the liquid flows and which is communicatively connected to the discharge ports. The channel-forming member includes a first layer and a second layer. The first and second layers are formed from negative-type photosensitive resin compositions containing a photopolymerization initiator. The first layer is located between the second layer and the substrate. The content of the photopolymerization initiator in the first layer is greater than the content of the photopolymerization initiator in the second layer.
