Abstract
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.
