A manufacturing method for an ink jet recording head. The method includes the steps of preparing a recording element substrate, preparing an electric wiring member, preparing a sealing material discharging member, and applying a sealing material. The ink jet recording head is constructed to provide a first gap between a recording element substrate and an inner edge of a hole. The first gap is larger than a second gap between the recording element substrate and an opposite inner edge of the hole measured along the same line. The sealing material is applied while moving the sealing material discharging member, along the line, from a portion of an electric wiring member adjacent to the first gap, across the first gap, across the electrical connection portions, across the second gap, to a portion of the electric wiring member adjacent to the second gap.
