<P>PROBLEM TO BE SOLVED: To provide a liquid supply structure which can prevent accumulation of bubbles effectively. <P>SOLUTION: In the liquid supply structure applied to a liquid ejection head which discharges liquid supplied through a filter, protrusions and recesses where the difference of height Ry between the highest portion and the lowest portion is √2 R/2 or more are formed repeatedly at a spatial frequency f of R or more and √2 R or less in the inner wall of the liquid supply structure along the flow direction of ink which flows in response to the discharge, on the assumption that the maximum dimension of the opening provided the filter is R. <P>COPYRIGHT: (C)2012,JPO&INPIT |
