PROBLEM TO BE SOLVED: To provide a microfluid chip for simplifying a mechanism, controlling a flow of a fluid, and correctly weighing the fluid accommodated in a cell. SOLUTION: In the microfluid chip 1 comprising: the weighing cell D11 having a fluid introduction port 11a for introducing the fluid into the weighing cell D11, and a fluid discharge port 12a for discharging the excess fluid exceeding the accommodation volume of the weighing cell D11; and a transfer control flow path LF11 coupled to the weighing cell D11 at one end, and deactivating a flow of the fluid by a Laplace force acting in the direction opposite to the direction of the flow of the fluid, the weighing cell D11 is filled with the fluid by deactivating the flow of the fluid flowing by a capillary phenomenon under the Laplace force applied to an end on the side of the accommodation cell D12 in the transfer control flow path LF11.
