PROBLEM TO BE SOLVED: To improve correction precision of misconvergence. SOLUTION: This deflection yoke device is a circuit in which first series circuit containing coils 1a, 1b for generating mainly a barrel magnetic field, coils 1c, 1d for generating mainly a pin magnetic field and a diode circuit 6 are connected in series, and provided with a second series circuit connected in parallel with the first series circuit. The diode circuit 6 is provided with a diode D1 whose anode is connected with an I/O node N5, a diode D2 whose anode is connected with a cathode of the diode D1 and whose cathode is connected with the node N5, a diode D3 whose anode is connected with the cathode of the diode D1 and whose cathode is connected with an I/O node N6, a diode D4 whose anode is connected with the node N6 and whose cathode is connected with an anode of the diode D2 and resistors R2, R3 connected in parallel with a parallel circuit of the diodes D3, D4.
