To prevent lowering of sensitivity of a flow cell based on total reflection of light at an outer face of a glass capillary at a joint part with a pipe, the flow cell includes, at joint parts with a pipe 605 to introduce solution to a glass capillary 601 and with a pipe to discharge solution from the capillary, an inorganic material layer 602 that reflects measurement light to modify the outer face of the glass capillary as well as a reinforcement layer 711 to modify the surface thereof. |
