An ink-jet head comprises a joint member having an ink outlet port out of which ink supplied from an ink supply source flows, and a passage unit having an ink receiving port that receives the ink flowing out of the ink outlet port of the joint member. A filter is disposed within a first ink passage inside the passage unit. The first ink passage extends in the same direction as an ink flow direction from the ink outlet port to the ink receiving port. In the first ink passage of the passage unit, a first space is formed between the ink receiving port and the filter, and a second space is formed contiguous to the first space with the filter interposed between the first and second spaces within the first ink passage. The cross-sectional shape and size of each space in a direction perpendicular to an ink flow direction are constant along the ink flow direction.
