There is provided a microchip, microchip controlling method and microchip controlling apparatus which have excellent flexibility in design of flow paths. The microchip comprises a plurality of laminated elastic sheets, wherein the elastic sheets are partially inadhesive each other so that at least 3 middle layers are formed; as a first middle layer, first flow path and second flow path through which liquid flows are formed; as a second middle layer, a first flow path opening/closing section for opening and closing the first flow path is formed; and as a third middle layer, a second flow path opening/closing section for opening and closing the second flow path is formed. |
