PURPOSE: An air-core reactor for shielding magnetic field is provided to prevent a malfunction of a relay, an operational error, and a trouble due to overheat by reducing effectively elements of harmonics. CONSTITUTION: An air-core reactor for shielding magnetic field includes a main body(32), a fixing member(31), a connection booth(34), an air-core reactor(30), a case, an auxiliary plate, and a ventilating fan. The main body(32) is used for restricting harmonics within a critical value. The fixing member(31) is used for fixing the main body. The connection booth(34) is used for connecting an input and an output terminal to a top end and a bottom end of the fixing member. The air-core reactor(30) includes a brass bar to fix the main body. The case is used for protecting the air-core reactor from the influence of the magnetic field. The auxiliary plate is formed at a rear side of the case. The ventilating fan is formed at the auxiliary plate.
