An ink storage chamber has a middle wall and a damper wall, which are in parallel to a flow direction of ink and which face each other vertically with a distance therebetween, and a surrounding wall surrounding a circumference of a space between the middle wall and the damper wall. On the middle wall, there is formed a pair of flow regulating ribs projecting toward the damper wall and extending substantially in parallel to the flow direction in a state of having a distance from the damper wall. A space sandwiched by the pair of flow regulating ribs is a main flow region, and spaces between the flow regulating ribs and the surrounding wall is sub-flow regions. A distance between the middle wall and the damper wall in the sub-flow regions is smaller than that in the main flow region. Accordingly, a wasted ink amount during purging can be reduced.
