Abstract
An ink-jet head according to the present invention includes a passage component, a filter, and a sealing member. The passage component defines an ink passage which includes a middle hole having an opening. The filter partitions the middle hole of the passage component into a first space and a second space. The sealing member seals the opening. The sealing member has a first region which is opposed to the filter with respect to the vertical direction. The filter is mounted to the passage component in such a manner that ink passing through the filter flows from the first space upward into the second space. A surface of the first region of the sealing member facing the ink passage has a portion which is inclined relative to a horizon.
