Further, winding collapse becomes more difficult to occur as the angle θ of the path of the winding pitch decreases, but on the other hand, as the angle θ decreases, the potential difference and the distribution capacitance appearing between the lines increase.

On the other hand, the angle θ with respect to this course is determined by the rate of increase in the number of turns in the repeated winding process. That is, in the above embodiment, each time the winding process of the first winding portion 22a is repeated, the reciprocating path is increased by the number of turns X of 4 turns on the reciprocating path.

In a method of winding an electric winding component wound between a collar of an iron core or a bobbin, a forward winding and a winding pitch are wound so that a winding pitch is advanced in one direction. The winding process in which the winding is performed with the same number of windings as the return winding is sequentially repeated, and each time the winding process is repeated, the number of windings in one direction is increased in one direction while increasing the number of windings in one direction. After forming a first winding portion by winding in a predetermined range from, the winding process of winding the return winding with respect to the forward winding by reducing the number of windings per fixed winding unit is sequentially repeated, A second winding portion is formed in a predetermined range between the first winding portion and the other flange, and subsequently, a winding process of winding the forward winding and the backward winding with the same number of windings is sequentially repeated. The second winding is performed while decreasing the number of windings by a fixed number of turns in the other direction each time the winding process is repeated. A third winding portion is formed by winding between the first portion and the other flange, while each of the above-described winding steps is performed with a winding interval having a length shorter than the wire diameter.

3. An electric winding part for winding a primary coil and a secondary coil between an iron core or a bobbin flange, wherein the forward winding and the winding pitch are wound in such a manner that the winding pitch is advanced in one direction. The winding process in which the winding is performed with the same number of turns as the return winding to be advanced is sequentially repeated. After forming a first winding portion by winding in a predetermined range from the flange of the winding, the winding step of winding the return winding with respect to the forward winding by reducing the number of windings in a unit of a fixed number of turns is sequentially performed A winding step of repeatedly forming a second winding portion in a predetermined range between the first winding portion and the other flange, and subsequently winding the forward winding and the return winding with the same number of turns, Repeatedly in turn, reducing the number of turns by a fixed number of turns in the other direction each time the winding process is repeated Winding is performed between the second winding portion and the other flange to form a third winding portion. Further, in each of the above-described winding processes, the winding is performed with a winding interval having a length shorter than the wire diameter. An electric winding component comprising: a secondary coil formed as described above; and a primary coil including an aligned winding wound to be an upper layer or a lower layer of the secondary coil.
