摘要： A flow path structure includes a heating element, a barrier layer, a liquid chamber formed by a part of the barrier layer and a pair of walls confronting each other to hold the heating element therebetween and a first individual flow path and a second individual flow path 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.

The liquid discharging units include ink chambers for containing liquid to be discharged, heating elements disposed in the ink chambers for applying flying force to the liquid, and a nozzle sheet having nozzles for discharging the liquid in the ink chambers. The common flow path supplies the liquid to the liquid discharging units. The liquid discharging units face the same direction in relation to the common flow path, and the nozzles of the liquid discharging units are disposed at a predetermined pitch. Adjacent nozzles are separated by a predetermined interval in a direction perpendicular to a direction of arrangement of the nozzles.

摘要： 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.
