In a multiply-twisted helix including having a hierarchical structure in which a linear structure as an element of a particular spiral structure is made of a thinner spiral structure, the spiral structures being bonded in at least one site at least between two layers, and the number of turns of the spiral structure of the lowest layer being N, the interval of bonds between m-th degree layers in the multiply-twisted helix is determined by the power function Ng(m) of N having an arbitrary linear function g(m)=betam+gamma (where beta and gamma are constant values and gamma<> 0) of m as its exponent.
