PROBLEM TO BE SOLVED: To reduce spurious radiation from a degaussing coil or an earth magnetism correction coil. SOLUTION: A common mode choke coil 8 connects to a degaussing device consisting of a degaussing coil 1 and a degaussing element (posistor) 9 to degauss a CRT to reduce spurious radiation from the degaussing coil being a component of the degaussing device, and another common mode choke coil 8 connects to an earth magnetism correction device provided with an earth magnetism correction coil 7 and an earth magnetism correction drive circuit 15 to reduce spurious radiation from the earth magnetism correction coil.
