The purpose of the present invention is to provide a device and method whereby it is possible to quantify a blood-vessel-(basal/basolateral)-side discharge fraction, a lumen-(apical)-side discharge fraction, and an intracellular retention fraction of a medicine administered to cells and thereby ascertain a distribution ratio in each fraction and assess an overall image of pharmacokinetics in vitro. As an example, the present invention provides a component analysis device characterized by being provided with a retaining part for retaining a plurality of containers for retaining liver cell tissue, and an analysis part for measuring a component supplied to the plurality of containers and analyzing the measured component, the plurality of containers being at least a first container and a second container, a first solution including a substance for releasing adhesion between a plurality of cells forming the liver cell tissue being retained in the first container, a buffer liquid being retained in the second contai
