A inner-wall-coated capillary in which a zwitterionic polymer including a phosphate group including, for example, a phosphorylcholine group, is fixed on a wall surface including, for example, silanol by ionic interaction, is obtained by flowing a polymer solution including a phospholipid polymer combining, for example, MPC and BMA or MPC and SMA, through a capillary that includes silanol on the wall surface, for example. Consequently, adsorption of phosphorylated compounds can be prevented simply and highly durably.
