PURPOSE: A refrigerator is provided to improve user convenience by controlling the sensitivity of an input button by controlling the electrostatic capacity of a variable capacitance part which is connected to the input button. CONSTITUTION: A refrigerator comprises: an input unit which includes a variable electrostatic capacity(420) which includes a plurality of capacitors and a plurality of switching elements and is electrically connected to the input button and a capacitance sensor which senses the varied electrostatic capacity; and a controller which controls the variable electrostatic capacity. The capacitance value of the variable electrostatic capacity is varied according to the ON/OFF operation of the switching elements. |
