This invention relates to a liquid jetting structure which comprises a nozzle or nozzles 11 for jetting a liquid 6. What is characteristic of this liquid jetting structure is that a flow path inside the nozzle or nozzles is set so that the degree of affinity for the liquid 6 to be jetted changes in the direction of liquid flow (140, 130). By controlling the affinity in this way, the liguid getting structure is possible to improve the linearity of advance of the liquid droplets, and to stabilize the liquid droplet diameter. Such a liquid jetting structure is suitable for an ink jet recording head.
