Claim:
A liquid-jet head comprising: a plurality of nozzles configured to eject liquid drops; a plurality of individual liquid chambers in communication with the nozzles; a common liquid chamber configured to supply the liquid to the individual liquid chambers; and a filter member configured to filter the liquid inside the common liquid chamber, wherein the common liquid chamber includes a first common liquid chamber member on an upstream side of the filter member, and a second common liquid chamber member on a downstream side of the filter member, the filter member includes (a) a thin layer comprising a plurality of pores and (b) a thick layer having at least a portion thereof disposed on a surface of a circumferential part of the thin layer, and said at least a portion of the thick layer disposed on the surface of the circumferential part of the thin layer is thicker than the thin layer, the thick layer of the filter member is bonded to the first common liquid chamber member, the thin layer of the filter member includes a first surface on which the thick layer is formed and a second surface opposite to the first surface, a circumferential part of the second surface of the thin layer being bonded to the second common liquid chamber member with an adhesive, among the pores formed in the thin layer of the filter member, at least some of the pores are formed in the circumferential part of the thin layer, said at least some of the pores formed in the circumferential part of the second surface of the thin layer include adhesive accumulating pores into which the adhesive overflowed, the adhesive accumulating pores into which the adhesive overflowed are exposed on a thick layer side of the pores, and the adhesive accumulating pores are disposed in an area of the thin layer which is between an area of the thin layer on which the thick layer is formed and an area of the thin layer where filter pores in which the liquid flows is formed.
