Provided is a method of manufacturing a recording head including a recording element substrate provided with an energy-generating element which generates energy used for discharging ink and an ink-supplying port through which ink is supplied to the energy-generating element, and a supporting member which supports the recording element substrate, the recording element substrate and the supporting member being bonded and fixed together by an ultraviolet curable adhesive, the method including applying ultraviolet light, along a line of intersection between a wall surface in the longitudinal direction of the ink-supplying port and a wall surface in the lateral direction of the ink-supplying port, toward a corner which is an intersection point among a side on the supporting member side of the wall surface in the longitudinal direction, a side on the supporting member side of the wall surface in the lateral direction, and the line of intersection.
