PURPOSE: A drier using microwave is provided to dry the manufactured woodwork without transformation of outer appearance in a short time and to control dry condition in real time. CONSTITUTION: A drier using microwave includes a power supply part(5) generating high frequency driving power supply, a magnetron(6) generating microwaves by receiving the driving power supply from the power supply part, a main body(9) having a space capable of receiving objects to be dried, a temperature sensor(3) sensing the change in the temperature of the objects, a load cell1 installed in the bottom of the objects received in the main body for sensing continuous change in weight of the objects, a controlling part(4) outputting signals for controlling the operation of the magnetron by receiving sensed results of the temperature sensor and the load cell, a memory device(2) storing information such as dry time and dry condition according to the kind of the objects and providing the information to the controlling part, an aspirator(7) sucking air of the main body and discharging into outside by receiving the power supply from the power supply part for decreasing the pressure of the main body, and a heater(8) increasing permittivity by preheating the objects according to the control signal of the controlling part.
