By providing a bobbin made of insulating material that covers each vertical deflection coil, and winding the horizontal deflection coil around this bobbin, it is possible to suppress variations in the magnetic field distribution due to the horizontal deflection coil and optimize it. At the same time, since at least a part of the horizontal deflection coil is close to the magnetic core with only the bottom plate of the bobbin in between, it is possible to significantly reduce the magnetic resistance that acts on the horizontal deflection magnetic field, increasing the efficiency of horizontal deflection. can be improved. Moreover, when the bobbin is attached to the magnetic core, the wall between the central bottom plate of the bobbin and the bottom plate near both ends in the circumferential direction presses the end of the vertical deflection coil, aligning the end positions of the vertical deflection coil. It is possible to correct variations in the vertical deflection coil, and to suppress variations in the magnetic field distribution due to the vertical deflection coil.
