PURPOSE: A humidity sensor for a microwave oven is provided to prevent a lower electrode layer from being reacted with a junction layer when the lower electrode layer is deposited. CONSTITUTION: A humidity sensor includes a humidity detecting device(101) for detecting humidity in a microwave oven, a compensation device(102) for compensating for a humidity value detected by the humidity detecting device(101), and a protecting case(103) for protecting the humidity detecting device(101) and the compensation device(102). The humidity detecting device(101) and the compensation device(102) are installed on printed circuit boards(110,110'). Insulation layers(120,120') are formed on the printed circuit boards(110,110'), respectively. Adhesive layers(130,130') are formed on the insulation layers(120,120').
