The purpose of the present invention is to provide a purification column that contains an adsorption carrier and shows excellent adsorption performance. In order to achieve the purpose, the present invention is provided with the following structure. Specifically, this purification column is provided with an adsorption carrier and a case that contains the adsorption carrier and has a tubular housing and treatment fluid supply port and discharge port at both ends of the housing. The purification column is characterized in that: a distribution plate is disposed at least on one end surface side of the adsorption carrier； the distribution plate has a plurality of openings that allow communication of the treatment fluid, a support body, and a protrusion extending from the support body to the adsorption carrier side； and at least part of the protrusion is inserted into the adsorption carrier.
