PROBLEM TO BE SOLVED: To provide a liquid jet head unit which enables nozzle openings to be arranged in a multi-row pattern, and which can enhance printing quality. SOLUTION: This liquid jet head unit comprises: a plurality of liquid jet heads 2 for emitting jets of liquids; a supporting member 220 for holding the liquid jet heads 2 by abutting on a head reference plane B specified on the basis of a liquid jet surface A in the liquid jet direction of each of the liquid jet heads 2; and a holding member 3 for holding the plurality of liquid jet heads 2 via the supporting member 220 by abutting on the supporting member 220. The holding member 3 is provided with a reference plane C which abuts on the supporting member 220 so as to position the plurality of liquid jet heads 2. The reference plane C is provided in such a manner as to be collinear with the head reference plane B in a planar direction. COPYRIGHT: (C)2008,JPO&INPIT
