Abstract: PURPOSE:To enable an effective correction for mis-convergence due to an alternate current loss by applying a good conductive flat metal plate of a non- magnetic material to a portion correspending to the magnetic field emission part of a cross arm in the funnel of a color image receiving tube. CONSTITUTION:In the funnel 3 of a color receiving tube 13, a portion corresponding to the vertical magnetic field emission part 1b of a cross arm 1 is applied with a good conductive flat metal plate 10 of a non--magnetic material. Vertical leak magnetic flux 9 emitted from the vertical magnetic field emission part 1b of the cross arm 1, therefore, penetrates the aforesald plate 10 and all the more eddy current 11 appears on the flat metal plate 10 when a retrace line period is shorter, thereby generating a magnetic flux 12.
