Zusammenfassung:	The present disclosure provides an adsorbent which is produced using a low environmental load material as a raw material and adsorbs selenious acid selectively and efficiently. A selenious acid adsorbent according to the present disclosure includes a cellulose derivative (I) having a repeating unit represented by Formula (I). In Formula (I), each Ra represents a hydrogen atom, a group represented by Formula (a-1), or a group represented by Formula (a-2), and at least one of all the Ras included in the cellulose derivative is a group represented by Formula (a-1) or a group represented by Formula (a-2):
