PROBLEM TO BE SOLVED: To provide a microchip device having the high functional liquid-liquid separation performance which has overcome the problems included in conventional techniques. SOLUTION: In the microchip device with a mechanism that two types of immiscible liquids are introduced into a detailed passage via different passages and passed within the detailed passage while forming two-laminar flow in contact with each other via the interface in the detailed passage, and then withdrawn through the different divided passages again, the detailed passage is characterized in that it is formed by bonding a first sheet-like member and a second sheet-like member after drilling a gutter to at least one of them, the hydrophilic chemical treatment is effected to the inner wall of the flowing side of the hydrophilic liquid in the detailed passage and the hydrophobic chemical treatment is effected to the inner wall of the flowing side of the hydrophobic liquid so that two types of liquids flow as the two-laminar flow, and in that a partition member jutted so as to divide the two-laminar flow from both sides along the interface of the two types of liquids is installed to the side walls of the detailed passage.
