PROBLEM TO BE SOLVED: To provide a deflecting yoke, which can aim at reduction of deflecting electric power and manufacturing cost and reduction of heat value, and cathode- ray tube equipment equipped with this. SOLUTION: A vacuum envelope has an almost truncated polygonal pyramid shaped yoke mounting part, and the deflecting yoke, which is placed on the yoke mounting part, is equipped symmetrically to its center axis, and has a pair of saddle type horizontal deflecting coils 30a and 30b, which are made to have the shape of the almost truncated polygonal pyramid. A separator 33 is formed in the perimeter side of the horizontal deflecting soils, and a magnetic body core 34 of a mostly truncated-cone shape is formed in the outside of the separator, in the same axis with the main axis. A pair of vertical deflecting coils is wound in a troidal manner to the magnetic body core. In a direction of a horizontal axis, which intersects vertically with the center axis of the horizontal deflecting coils, the relation, which the maximum diameter on the vertical axis of the horizontal deflecting coils > the maximum diameter of the vertical axis on the core is filled.
