PROBLEM TO BE SOLVED: To provide a micro fluid chip and a mixing method for preventing air bubbles from being mixed in a fluid received by the chip. SOLUTION: The micro fluid chip 1, making a plurality of weighing cells D1, D2 receive the predetermined fluids, and weighing them to transfer the fluids received by the weighing cells D1, D2 to a mixing cell M1, and mix them, includes: a transfer control flow path LF11 provided between the weighing cells D1, D2, connecting the weighing cells D1, D2 in series, and controlling a flow of the fluid by a Laplace force; a transfer control flow path LF12 for connecting a last stage of the weighing cells D1, D2 connected by the transfer control flow path LF11 to the mixing cell M1, and controlling the flow of the fluid by the Laplace force; and a discharge port 12c provided at an end in the flow direction of the fluid flowing in the mixing cell M1.
