PURPOSE:To obtain a good workability for a device, by forming at least the first layer winding of the ferrite core windings for each semicircumferential section into a normal winding state and the next layer into a bias winding state. CONSTITUTION:Of the windings 21, for instance, their first-second layer windings are formed into a normal state of winding on a ferrite core 20. In such a case as formed in a normal state of winding, the winding 21 is placed at a right angle to the end part of the ferrite core 20, causing no slippage of the winding. And then windings of the third layer and after are formed into a bias state of winding. In this way, after the state of normal winding, the state of bias winding in which a winding angle at the side of a neck part and that at the side of a cone part are different is formed, thus to change the characteristic of convergence and deflection sensitivity. |
