PURPOSE:To provide an inexpensive and small-sized ink jet print head which can stably carry out color print with high quality. CONSTITUTION:A pressure chamber block 28 in which a plurality of colors of monochromatic pressure chambers 14 are arranged in a specified order is formed. A plurality of the blocks 28 are arranged in a line state to form multi- color pressure chambers. Since specified colors of inks are supplied from a common ink channel 30 of ink colors disposed in parallel with the arranging directions of the blocks to the chambers 14 including the chambers via an ink supply passage having an ink narrow passage 40, a bridge channel 42 and a vertical channel 43, a color printing of one line can be performed by one scanning of one row of print heads, thereby the ink jet print head can be miniaturized. |
