<p>A liquid jet recording head has a recording element unit that has a recording element substrate and a flexible film member electrically connected to the recording element substrate, a support member on which the recording element substrate is fixedly held, and a support plate situated between the flexible film member and the support member and fixedly holding the flexible film member. A first thermosetting resin agent, which retains elasticity even after being hardened, is filled into recesses formed around the recording element substrate within an opening of the flexible film member and an opening of the support plate, and electrical connection areas between the recording element substrate and the flexible film member are coated by a second thermosetting resin agent, which has a higher mechanical strength after being hardened than that of the first resin agent. The recording element substrate is protected from damage due to shrinkage of the resin agent, filled around the recording element substrate, during hardening, and the electrical connection area between the recording element substrate and the flexible film member can be protected against external forces. <IMAGE></p> |
