A treated waste has been treated so as to prevent diffusion of a substance to be disposed, of e.g., radionuclide &ldquo;I&rdquo;, that tends to occur when the waste is disposed of in reducing environment at an ultra-deep underground. The treated waste has a low-resolution compound containing &ldquo;I&rdquo;, e.g., &ldquo;AgI&rdquo;, and a high oxygen potential agent having a higher oxygen potential than the compound, e.g., &ldquo;Fe,O,&rdquo;. Ionization of the substance to be disposed, attributable to reduction of the compound, can be suppressed over a long time.
