Color cathode-ray tube apparatus

An insulating frame of a deflection yoke is fixed to a funnel with a metal band and a metal screw. A partition formed so as to be integrated with a holder holding a magnet ring of a CPU includes a first partition provided on a first axis so as to hide the metal screw when the deflection yoke is seen from the holder side along a tube axis, and a second partition provided on a second axis orthogonal to the first axis. A height H1 of the first partition, a height H2 of the second partition, a minimum height Hmin of the partition, a height HM of a pull of a magnet ring on a side closest to the deflection yoke, and an outer circumferential edge diameter RM of the magnet ring excluding the pull satisfy relationships: H1>H2, HM-H2>10 mm, and Hmin>RM. Because of this, a discharge between a metal band and a metal screw that fix the deflection yoke, and a velocity modulation coil can be prevented without decreasing the operability of the rotation adjustment of the magnet ring of the CPU.
