PURPOSE: To ensure that electric parts can be coated by dripping using a specified amount of discharged curable liquid material even when a small-size storage tank is used by providing a control part which adjusts a pressure in accordance with variations of the rotation of a rotor and making a discharged amount constant in response to the viscosity change of the curable liquid material.

CONSTITUTION: This discharge device of curable liquid material is equipped with magnetic field generation stators 41a to 41c, a rotor 42 and a means for measuring the number of rotations of the rotor 42 provided at the lower end of a storage tank 1. Further, the discharge device is equipped with a control part 5 which adjusts the pressure of gas from a gas supply source 31 in accordance with the variations of the number of rotations and makes the discharged amount of the curable liquid material constant. Consequently, a rotary torque generates on the rotor 42 on account of the magnetic field generation stators 41a to 41c, and the rotor 42 rotates under the viscous resistance of the curable liquid material. Thus, the rotating speed of the rotor 42 is controlled to be a function of the viscosity of the curable liquid material so that the gas pressure is controlled by the rotating speed so as to allow the discharged amount constant regardless of the viscosity change of the curable liquid material.
