PURPOSE:To prevent the lowering in the function and reliability of a recording head and to further promote the densification of orifices by reducing possibility for generating shortcircuit between adjacent electrodes, by arranging a first electrode to the surface provided with a heat generating resistance layer of a substrate and arranging a second electrode to the surface thereof other than said surface. CONSTITUTION:A heat generating resistance layer 311 and a selection electrode 314 are laminated to the upper surface of a substrate 303 in order from the substrate side. The heat generating resistance layer 311, a common electrode 313 and the selection electrode 314 are respectively patterned at desired positions in a predetermined shape and size such that a heat generation part 308 is arranged between the common electrode 313 and the selection electrode 314. The common electrode 313 is connected to the heat generating resistance layer 311 at the terminal part thereof and this terminal part is integrated with a conductive support 315 through the electrode in a through-hole 317 while the selection electrode 314 is arranged only to the upper surface of the substrate 303. Therefore, the common electrode 313 and the selection electrodes 314 are arranged to the front and back surfaces of the substrate in a separated state through an insulating layer 310. Because the common electrode and the selection electrode are arranged in a separated state as mentioned above, densification is enabled and a structure hardly generating shortcircuit between electrodes is formed. |
