ABSTRACT:
An ink-jet head comprises a reservoir unit that includes an ink reservoir. The reservoir unit includes an introduction passage that connects an ink introduction port and an inflow port facing the ink reservoir, and a filter that extends within the introduction passage. The introduction passage has such a configuration that, on both sides of the filter, ink can flow along the filter toward the inflow port. An ink non-passing area is formed within the reservoir unit. The ink non-passing area extends continuously, from at least a part of an area on a plane of the filter opposed to the inflow port, in a direction away from the inflow port.
