Abstract: Provided is a column tube for chromatography that can prevent a peak shape abnormality referred to as a foot in a resulting chromatogram. The object is accomplished by the column tube for chromatography, through which a fluid flows, this column tube including a plurality of polishing traces extending on an inner circumferential surface of the column tube in a flow direction of the fluid.
