PROBLEM TO BE SOLVED: To provide an enrichment means of particulate dispersion and an enrichment device thereof enriching particulate dispersion containing electrophoresed particulate with low energy, highly efficiently in a short time with a high recovery ratio. SOLUTION: This enrichment device has a flow passage of a minute width, and electrodes 12 applying an electric field to the direction crossing the flow passage. The flow passage of the minute width has an introducing part 2 introducing the particulate dispersion located on one end, a liquid sending part 4 sending the particulate dispersion introduced from the introducing part toward the other end in a laminar flow, a particulate moving part 6 moving particulate in the passing dispersion by application of the electric field toward one direction of the electric field, a recovery part 8 recovering the particulate dispersion in the moving side of particulate, and a discharge part 10 discharging liquid other than the particulate dispersion recovered in the recovery part.
