PURPOSE:To easily form an ultra-conductive substance comprising a two-element compound, by subjecting an element such as V, Nb, Ti, Hf or Zr, an element such as Si, Ge, Sn, Al or Ga and a compound containing O, N or S to solid phase reaction. CONSTITUTION:An element A such as V, Nb, Ti, Hf or Zr, an element B such as Si, Ge, Sn, Al or Ga and a compound BCx containing a highly reactive element C such as O, N or S are subjected to solid phase reaction to form an ultra- conductive substance AyB (wherein V3Si formed by using SiO2 as BCx is excepted) comprising a two-element compound. In this case, the element A is reacted with C in the compound BCx and, at the same time, decomposes BCx to form AyB and B is not supplied except for the decomposition of BCx and, therefore, reaction advances in such a state that the supply amount of B is limited and (y) takes a value of 1 or more, in general, 3.
