摘要： A classifying apparatus (1) has a flow path (structure) through which an emulsion flows. The flow path is provided between at least two plates (upper plate (2), lower plate (4)) that are separated by a distance smaller than the largest diameter of a liquid droplet included in the emulsion. Emulsion is fed from a supply port (5) provided in the upper plate (2) and can be classified by passing it in the flow path.
