Abstract
A liquid chromatography column comprising: a column tube including a flow path that runs therethrough in an axial direction of the column tube and that is filled with a filler; a filter unit that is mounted at an axial direction end of the column tube to trap the filler inside the flow path; and a cap that includes a through hole communicated with the flow path through the filter unit and that is mounted at the column tube, wherein a gap, which is a space into which the filler overflowing from the flow path can escape when the cap is being attached to the column tube, is formed at an outer side of a contact surface at which the column tube and the filter unit contact each other.
