ABSTRACT:
A deflection apparatus arranged on the outer circumference of a funnel of a cathode ray tube includes a deflection yoke having vertical deflection coils and horizontal deflection coils. A compensation coil is provided on the outer circumference of a front end opening portion of the deflection yoke. An electrostatic capacitance element is connected between both end terminals of the compensation coil. The capacity of the electrostatic capacitance element is set such that an inducing voltage generated between both end terminals of the compensation coil is equal to or lower than a predetermined value.
