PROBLEM TO BE SOLVED: To provide a cathode-ray tube device capable of making a dynamic convergence adjustment easy and having an excellent convergence characteristics without mounting an additional correction coil and requiring a special correction circuit for generating correction current. SOLUTION: A horizontal deflection coil is wound by a conductive wire and, as for the vertical section area of a tube axis, separated into sections by predetermined angle ranges and centering a winding angleθ1 that defines the horizontal direction of an electron gun side area as 0°, a winding angleθ2 that defines the horizontal direction of a middle area as 0°, and a winding angleθ3 that defines the horizontal direction of a screen side area as 0°C. The line density of a lead wire of the first section is less than that of other sections and the winding angleθ1, the winding angle #2, the winding angleθ3 satisfy the following relation;θ1≥θ2≥θ3.
