There is disclosed an adsorbent for an oral administration, comprising a spherical activated carbon prepared from a thermosetting resin as a carbon source, wherein a diameter is 0.01 to 1 mm, and a specific surface area determined by the Langmuir's adsorption equation is not less than 1000 nr/g; and an adsorbent for an oral administration, comprising a surface-modified spherical activated carbon prepared from a thermosetting resin as a carbon source, wherein a diameter is 0.01 to 1 mm, a specific surface area determined by the Langmuir's adsorption equation is not less than 1000 m2/g. a total amount of acidic groups is 0.40 to 1.00 meq/g, and a total amount of basic groups is 0.40 to 1.10 meq/g are disclosed. The orally-administrating adsorbents exhibit useful selective adsorbability, that is, a less adsorbability of useful substances in body, but more adsorbability of toxic substances.
