    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.

    摘要： A liquid ejection head includes a plurality of liquid ejection elements arrayed in a flat area on a substrate. Each liquid ejection element includes a liquid chamber, a heating element disposed in the liquid chamber, and a nozzle. The heating elements are disposed alternately on a first and second lines spaced by δ in a zigzag fashion. Each liquid chamber is formed to have a U-like shape in horizontal cross section such that a wall thereof surrounds three sides of a heating element disposed in each liquid chamber. A gap Wx is formed between each two adjacent liquid chambers located on the second line, and a gap Wy is formed between the liquid chambers located on the first line and the liquid chambers located on the second line. The gaps Wx serve as first common flow channels, and the gap Wy serves as a second common flow channel.

    摘要： A liquid ejection head includes a plurality of liquid ejection elements arrayed in a flat area on a substrate. Each liquid ejection element includes a liquid chamber, a heating element disposed in the liquid chamber, and a nozzle. The heating elements are disposed alternately on a first and second lines spaced by 6 in a zigzag fashion. Each liquid chamber is formed to have a U-like shape in horizontal cross section such that a wall thereof surrounds three sides of a heating element disposed in each liquid chamber. A gap Wx is formed between each two adjacent liquid chambers located on the second line, and a gap Wy is formed between the liquid chambers located on the first line and the liquid chambers located on the second line. The gaps Wx serve as first common flow channels, and the gap Wy serves as a second common flow channel.
