    摘要： A cathode-ray tube apparatus capable of reducing a high frequency electric field radiated from the deflection yoke (3) and the deflection and high voltage circuit (4) to the outside of the cathode-ray tube apparatus (1). Mounted on the deflection yoke (3) or on the cathode-ray tube (2) are an induction coil (10) for generating a pulse voltage (e2) opposite in polarity to a high pulse voltage (e1) applied to the h (8) and an electric field cancellation electrode (6) made of a conductive wire to which the opposite polarity pulse voltage is applied. When the opposite polarity pulse voltage (e2, e3) is applied to the electric field cancellation electrode (6), the electric field cancellation electrode (6) radiates an electric field opposite in polarity to the high frequency electric field radiated from the deflection yoke (3) to the outside of the cathode-ray tube apparatus (1) to reduce the intensity of the high frequency electric field.
