Liquid jet recording head and method of manufacturing the same
A liquid jet recording head has a recording element unit that has a recording element substrate, a flexible film member electrically connected to the substrate, a support member on which the substrate is fixedly held, and a support plate between the flexible film member and support member fixedly holding the flexible film member. A first thermosetting resin agent, which retains elasticity even after being hardened, is filled into recesses 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 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 substrate is protected from damage due to shrinkage of the resin agent, and the electrical connection area between the substrate and the flexible film member can be protected against external forces.
