PROBLEM TO BE SOLVED: To provide a paste coater preventing a nozzle clogging. SOLUTION: The paste coater is provided with a nozzle body 1 and a needle 3. A nozzle hole 23 spraying the paste is drilled on an apical surface of the nozzle body 1. The needle 3 has a valve portion 33 which abuts to an inner peripheral surface 22 of the nozzle body connecting to the nozzle hole 23 and blocks the nozzle hole 23, and an inserting portion 34 extending further from the valve portion 33. The inserting portion 34 can be freely inserted into and removed from the nozzle hole 23, and is formed in the length exposing outside from the apical surface of the nozzle hole 23. Further, a gas jetting mouth 25 is formed on the outer edge circumference of the nozzle hole 23, and a negative pressure is formed in the vicinity of the opening of the nozzle hole 23 by the gas sprayed from the gas jetting mouth 25.
