PROBLEM TO BE SOLVED: To prevent the trouble of the risk that, for example, an IC is broken by heat generation. SOLUTION: The fluid jetting apparatus includes: a plurality of driving signal generation parts which respectively generate driving signals for driving elements that make a fluid jet from nozzles; a plurality of temperature sensors which detect temperatures of the driving signal generation parts; and a control part which makes the driving signal generation parts generate the driving signals. The control part makes the driving signal generation part wait for generation of the driving signal when the detected temperature of the temperature sensor exceeds a first threshold value. The control part determines the first threshold value according to the number of the temperature sensors of detected temperatures which is higher than a second threshold value and lower than the first threshold value.
