The objective of the present invention is to provide a container for easily and efficiently purifying a target biomolecule from a cell culture liquid or a body fluid and a method for purifying a target biomolecule by using the container. The purification container for a target biomolecule from a cell culture liquid or a body fluid is characterized by comprising an inlet, a filter and an outlet, and further comprising an adsorbent for adsorbing an impurity and/or an aggregating agent for aggregating an impurity, wherein the filter captures the impurity adsorbed on the adsorbent and/or the impurity aggregated by the aggregating agent.
