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.本發明目的在於提供：收容吸附載體的純化管柱，能獲得優異吸附性能的純化管柱。為解決上述課題，本發明係具有下述構成。即，本發明的純化管柱，係具備有吸附載體與框體；該框體係收容上述吸附載體，設有筒狀外殼、與在上述外殼二端設有處理流體的供應接口及排出接口；其特徵為，在上述吸附載體的至少一端面側配置分配板；上述分配板係設有：處理流體可連通的複數開口部、支撐體、以及從上述支撐體朝上述吸附載體側延伸出的凸部；上述凸部的至少一部分係插入於上述吸附載體中。
