PURPOSE: An electrode device, which is applied with a water cooling method which can circulates water in only an electrode device, is provided to form the path which circulates the gas which is indirectly cooled by the cooling water in a coil. CONSTITUTION: An electrode device comprises a first electrode terminal part(210) and a second electrode terminal part(220). The first and second electrode terminal parts are respectively connected to a coil in order to offer the induction power to the coil. The coil heats the objects through the heat of resistance by the electromagnetic induction. The first electrode terminal part receives and discharges cooling water after circulation. The first electrode terminal part indirectly cools the gas, provided from outside, using the circulation of the cooling water circulating. The first electrode terminal part supplies the gas cooling to the coil. The second electrode terminal part discharges the gas cooling to outside.
