Abstract
A liquid jet head can be detachably fitted into an opening portion of a liquid tank having a liquid absorbing member therein by a liquid receiving member with a liquid path formed therein. The liquid head has a filter, and the peripheral part of the filter is immovably embedded in the foremost end of the liquid receiving member such that the radially outermost end of the filter is not exposed, and the filter is maintained so as to have a dome-shaped contour adapted to come in pressure contact with the liquid absorbing member when the liquid jet head is fitted to the liquid tank by the immovable embedding of the peripheral part of the filter therein. A liquid jet apparatus with a liquid tank has a liquid absorbing member and an opening portion formed thereon, as well as a liquid jet head of this type. A method of immovably securing a filter to a liquid receiving member of a liquid jet head is also described.
