PROBLEM TO BE SOLVED: To solve a problem wherein accurate measurement is not carried out because a light beam is scattered by bubbles, when the bubbles stay in a channel or on a window wall of a liquid sample flow cell in the optical measurement by a polarimeter, a spectrophotometer or the like. SOLUTION: The bubble staying in the channel and on the window wall of the flowing liquid is made to float and to flow out, by using hydrophilic resin material as a material for the channel and the window wall, in the liquid sample flow cell. The liquid sample flow cell is not required thereby to provide an additional device for maintenance and removal of the bubble by taking out the liquid sample flow cell from a device.
