Abstract
A deposition of bubbles or foams to an inner wall of a liquid supplying member is prevented, thereby improving ejecting performance of the bubbles or foams. In the liquid supplying member which forms a flow path for supplying a liquid to a liquid discharging apparatus, the inner wall surface has a concave/convex shape in which a mountain portion and a valley portion are repeated at a predetermined spatial frequency. Assuming that an opening diameter of a filter provided for the liquid discharging apparatus is equal to R (μm), one period f (μm)of the spatial frequency lies within a range from R or more to √{square root over (2)}·R or less and a maximum height Ry (μm) of the mountain portion is equal to √{square root over (2)}·R/2 or more.
