Abstract:
1. A liquid discharge recording head, comprising: a recording element substrate that has a recording element that generates energy for discharging a liquid, an electric wiring board that is electrically connected with the recording element of the recording element substrate and that has an opening part formed therein, and a supporting plate that supports the recording element substrate and the electric wiring board, wherein the recording element substrate is arranged at the opening part of the electric wiring board such that a gap is formed between the recording element substrate and the electric wiring board; a connecting member that electrically connects, across the gap, an electrode provided in the recording element substrate and an electrode terminal provided in the electric wiring board; and a first resin agent that is provided in the gap between the recording element substrate and the electric wiring board, a second resin agent that seals the electrode of the recording element substrate, the electrode terminal of the electric wiring board, and the connecting member, and contacts with a surface of the first resin agent that is on an opposite side to the supporting plate, and a third resin agent that is provided between the first resin agent and the supporting plate and that has a lower modulus of elasticity than that of the first resin agent and the second resin agent, wherein the third resin agent is not fixed to the supporting plate.
