PURPOSE: To provide a deflection yoke capable of correcting a YH cross misconvergence without causing VCR narrow misconvergence. CONSTITUTION: A correction circuit 15A consists of: first to fourth magnetic field correction coils 1 to 4; and a 3-terminal variable resistor 20, and is configured such that a series circuit comprising the first and the second magnetic field correction coils 1, 2 is connected in parallel with a series circuit of the fourth and the third magnetic field correction coils 4, 3 connected to two respective fixed terminals of the 3-terminal variable resistor 20, the moving terminal T1 is connected to a connecting point P of the first and second magnetic field correction coils 1, 2, vertical deflection coils 12, 13 are connected in series with the first and second magnetic field correction coils 1, 2, the first and third magnetic field correction coils 1, 3 are wound on a first core 14A, the second and fourth magnetic field correction coils 2, 4 are wound on a second core 14B, and the first and second cores 14A, 14B are placed opposite to each other while sandwiching a neck part 51c.
