Ink-jet head and ink-jet printer

An ink-jet head comprising:

• a flow passage member including:
• a first common flow passage extending in a first direction;
• a first ink supply port communicated with the first common flow passage;
• a plurality of first individual flow passages each connected to the first common flow passage and aligned in the first direction;
• a second common flow passage extending in the first direction and positioned to be deviated from the first common flow passage in a second direction orthogonal to the first direction;
• a second ink supply port communicated with the second common flow passage;
• and a plurality of second individual flow passages each connected to the second common flow passage and aligned in the first direction;
• a plurality of first pressure generators aligned in the first direction and configured to generate pressure to ink contained in the first individual flow passages;
• a plurality of second pressure generators aligned in the first direction and configured to generate pressure to the ink contained in the second individual flow passages;
• a first conductive part configured to be electrically connected to the first pressure generators and a control circuit;
• and
• a second conductive part configured to be electrically connected to the second pressure generators and the control circuit;
• wherein the first ink supply port is positioned on one side in the first direction with respect to the first individual flow passages and the ink is supplied to the first common flow passage only from the first ink supply port, and the second ink supply port is positioned on the other side in the first direction with respect to the second individual flow passages and the ink is supplied to the second common flow passage only from the second ink supply port, and
• an end portion of the first conductive part positioned nearer to the control circuit is positioned on the one side in the first direction with respect to the first pressure generators and an end portion of the second conductive part positioned nearer to the control circuit is positioned on the other side in the first direction with respect to the second pressure generators, or the end portion of the first conductive part positioned nearer to the control circuit is positioned on the other side in the first direction with respect to the first pressure generators and the end portion of the second conductive part positioned nearer to the control circuit is positioned on the one side in the first direction with respect to the second pressure generators.
