PROBLEM TO BE SOLVED: To realize a microchip capable of bringing a plurality of kinds of liquids to flow into each other and then branching them at a prescribed mixture ratio, even if the length of its mixing channel is short. SOLUTION: The microchip includes: a first inflow channel 101 for bringing first liquid to flow into a confluence section JC; a second inflow channel 102 and a third inflow channel 103 for bringing second liquid different from the first liquid to flow into the confluence section from an area being in the same plane as and on both the sides of the first inflow channel; an intermediate channel 110 for feeding the first liquid and the second liquid from the confluence section JC to a branch section SP, in the state of a laminar flow; a first outflow channel 111 for branching the confluent liquid of the first liquid and the second liquid fed from the second inflow channel 102 from the branch section SP, while keeping the laminar flow state from the confluence section JC; and a second outflow channel 112 for branching the confluent liquid of the first liquid and the second liquid fed from the third inflow channel 103 from the branch section SP, while keeping the laminar flow state.
