PROBLEM TO BE SOLVED: To provide a multi-array ink jet print head provided with a minimum number of ink supply passages and having a narrow width in the short side direction. SOLUTION: Nozzle arrays 26 are arranged on the master substrate 21 of a print head 20 while inclining at an angleθwherein thirteen print chips 22 in an array constitute a subhead 23 (23-1, 23-2, 23-3 or 23-4). Vertically or laterally adjacent print chips 22 are interlaces obliquely between subheads 23 and no useless gap is present. The print head 20 has width J in the short side direction which is narrower than that of a conventional multi-array print head. Each subhead 23 corresponds to one ink supply passage 24 (24-1, 24-2, 24-3 or 24-4) and total four ink supply passages 24 communicate, respectively, with four ink storage chambers of yellow Y, magenta M, cyan C and black K of one ink tank.
