PURPOSE:To reduce the size of a deflector by using misconvergence raster strain correction magnets each consisting of a plate magnetized in such a manner as to produce opposite magnetic poles in the ends of each of the front and the back surfaces. CONSTITUTION:The misconvergence raster strain correction magnet 1 of an inline-type color cathode-ray tube is a thin plate which is magnetized in such a manner as to make the ends (2A1) and (2A2) of the surface 2A of the magnet 1 an N pole and an S pole respectively and to make the ends (2B1) and (2B2) of the back surface 2A of the magnet 1 an S pole and an N pole respectively. The deflector of this invention is made by symmetrically attaching four correction magnets 1 to a separator 13 installed between the horizontal and the vertical deflection coils 11 and 12. Accordingly, it is possible to apply a correction magnetic field with adequate intensity to the electron beam by reducing the thickness of the magnets 1 so as to effectually utilize the space.
