A multiplex winding helical structure in which the element of helical structure, i.e. a linear structure, has a hierarchic structure comprising a finer helical structure, at least two hierarchic helical structures are jointed at at least one point, and the helical structure of lowermost layer has a number of turns of N. Interval of joint between m-order hierarchies is determined by a width function N<g(m)> of N having an arbitrary linear function g(m)= beta m+ lambda ( beta and lambda are constants and lambda ≠ 0) as an index. Electronic correlation in an electronic system on the helical structure is controlled by setting beta or lambda at a specified value.
