Abstract: One embodiment of the present invention relates to a sealing system having a leakage sensing function. A leakage sensing unit is arranged in a sealed space which is formed between sealing members of a sealing device body so as to sense, in real time, whether the sealing members are leaking, wherein a sensing value of the leakage sensing unit can be transmitted to the outside by using a communication unit.
