Liquid jetting head

A liquid jetting head, comprising:

• a channel substrate having a nozzle surface in which nozzles are open, the channel substrate being formed with pressure chambers communicating with the nozzles respectively;
• and
• an actuator covering the pressure chambers,
• wherein the pressure chambers include first pressure chambers arranged in an arrangement direction to form a first pressure chamber row in the channel substrate,
• each of the first pressure chambers has a first end on one side in an orthogonal direction and a second end on the other side in the orthogonal direction, the orthogonal direction being parallel to the nozzle surface and orthogonal to the arrangement direction,
• the nozzles include first nozzles communicating with the first pressure chambers respectively,
• any two first nozzles, which are included in the first nozzles and adjacent to each other in the arrangement direction, are arranged at different positions in the channel substrate with respect to the orthogonal direction and different in a first distance, the first distance being a distance in the orthogonal direction between each first nozzle and the first end of each first pressure chamber communicating with the first nozzle,
• the first nozzles include farthest two first nozzles that are separated from each other farthest with respect to the orthogonal direction, and
• a second distance in the orthogonal direction between the farthest two first nozzles is not less than a third distance, the third distance being a distance between each of the farthest two first nozzles and a nearest end of each first pressure chamber communicating with the first nozzle, the nearest end of the first pressure chamber being one of the first end and the second end which is nearer to the first nozzle in the orthogonal direction.
