PROBLEM TO BE SOLVED: To provide a fluid jetting apparatus for droplet amounts corresponding to various resolutions and efficiently fulfilling the technical requirements of a high-performance print system. SOLUTION: In relation to an emission chamber 301, a first droplet jetting device 303 is provided with a first heating element, and the first droplet jetting device is configured so as to jet out fluid having a first droplet amount from the emission chamber. A first hole 317 relevant to the first droplet jetting device is disposed in an orifice layer 305 adjacent to the first droplet jetting device. In relation to the emission chamber, a second droplet jetting device 304 is provided with a second heating element, and the second droplet jetting device is configured so as to jet out fluid having a second droplet amount from the emission chamber. A second hole 319 relevant to the second droplet jetting device is disposed in the orifice layer adjacent to the second droplet jetting device. A voltage supply 310 is electrically connected with the first droplet jetting device and the second droplet jetting device in series. The voltage supply is configured so as to generate a first voltage for individually actuating the first droplet jetting device, and a second voltage for actuating the first droplet jetting device and the second droplet jetting device approximately at the same time.
