摘要： A liquid chromatographic column includes: a cylindrical column body; an inflow-side filter that is disposed at an eluent inflow-side end of the column body; an outflow-side filter that is disposed at an eluent outflow-side end of the column body; and a filler that is filled between the inflow-side filter and the outflow-side filter, in which the inflow-side filter has a two-layer structure consisting of a first resin filter member and a second resin filter member which are disposed in this order from a side of the filler, and the first resin filter member has an indentation elastic modulus lower than that of the second resin filter member.
