    Abstract: A flow path structure includes a heating element (12), a barrier layer (13), a liquid chamber (13a) formed by a part of the barrier layer and a pair of walls (13b) confronting each other to hold the heating element therebetween and a first individual flow path (13d) and a second individual flow path (13e) disposed on both the sides of the liquid chamber to communicate with the liquid chamber, a liquid is supplied to the liquid chamber from at least one of first and second individual flow paths, and the distance U between the walls in the liquid chamber and the flow path width W of the first individual flow path are set to satisfy U > W. With this arrangement, a flow path structure can be provided in which a failure in flow paths due to dusts is unlike to occur and which minimizes the influence of bubbles and has almost no uneven ejection.

    Abstract: Heat-generating elements are formed by depositing at least a IV A metal layer (Ti,Zr,Hf) or a V A metal layer (V,Nb,Ta), followed by depositing a resistor material thereupon. Thus, the reliability of heat-generating elements applied to thermal type ink-jet printers, for example, is improved as compared to conventional arrangements.

    Abstract: In a liquid ejection apparatus including a plurality of chips arranged in-a specific direction, each chip including a plurality of liquid ejection units juxtaposed in the specific direction, the displacement of liquid landing position in the specific direction is reduced. A printer head chip includes a heating resistor, which is divided into two and arranged within one ink liquid chamber. The two-divided heating resistors within the one, ink liquid chamber are juxtaposed in a direction perpendicular to the lining-up direction of nozzles.

    Abstract: The invention provides a printer, a printer head, and a method of producing the printer head. In particular, the invention is applied to a printer which makes use of a process in which ink drops are caused to flow out by heating using a heater, so that an orifice plate can be bonded by sufficiently bringing it into close contact with what it is to be bonded to. In the invention, by disposing first, second, and third wiring patterns below partitions of corresponding ink chambers, thickness-direction stepped portions are prevented from being formed at at least the partitions of the corresponding ink chambers.
