PROBLEM TO BE SOLVED: To provide a fluid jetting device jetting fluid.SOLUTION: A fluid jetting device for jetting fluid in a pulse state, includes: a jetting flow passage having a jetting port through which fluid is jetted; an actuator which applies a pressure on fluid supplied from the outside and sends a pulse flow to the jetting flow passage; a suction flow passage which is provided with a suction port capable of sucking the fluid therein; and a container which stores part of the suction flow passage and the actuator and from one end of which the jetting flow passage is extended. The jetting flow passage is disposed close to the suction flow passage at the side of the jetting port, is curved in the container and separates from the suction flow passage. The suction flow passage is formed into a linear state or a curved line state having a curvature smaller than that of the curve of the jetting flow passage. |
