Two adjacent pressure chamber columns constituted by a first pressure chamber column and a second pressure chamber column are arranged opposite to each common ink path. First connection holes formed in the pressure chambers of the first pressure chamber column and connected to nozzles and second connection holes formed in the pressure chambers of the second pressure chamber column and connected to nozzles are arranged side by side on opposite sides of a corresponding common ink path. Between two adjacent common ink paths, first connection holes and second connection holes are arranged on a column.
