A remover of electrostatic charges comprises a head part, a soft X-ray protecting part, and a power controlling part. The head part neutralizes and weakens electrostatic charges of bodies that are objects of removal of electrostatic charges by generating soft X-ray having wavelengths in the range of 1.2 Ř1.5 Šwith high energy from a soft X-ray tube, and ionizes gas molecules directly and also removes electrostatic charges in atmosphere of inert gases (N2, Ar). The soft X-ray protecting part wraps the head part and prevents that soft X-ray is leaked from said head part. The power controlling part is connected to the head part and the soft X-ray protecting part electrically and provides target voltage to control the ion generation of filament voltage of a soft X-ray tube and soft X-ray tube with the soft X-ray tube.
