To provide a paste applying device and a paste applying method capable of stably applying a paste with excellent responsiveness.

In the paste applying method by introducing the paste 7 stored in a syringe 17 through a tube 18 and discharging it from a discharge port, the vibration in the direction along the tube 18 is imparted by a vibration imparting means composed of a piezoelectric element 22. At this time, the paste in the tube 18 is discharged from the discharge port by setting the max. rate v1 of the vibration at the time of displacing in the discharge port direction to be larger than the max. rate v2 at the time of displacing in the opposite direction by controlling the speed pattern of the vibration of piezoelectric element 22 by a control means. As a result, the paste 7 is applied on the material to be coated by stably discharging with the excellent responsiveness.
