PROBLEM TO BE SOLVED: To provide a microchemical system in which a stream of a sample solution flowing through a flow passage of a microchip can be controlled. SOLUTION: This microchemical system 1 is provided with the microchip 7 having a T-shaped flow passage 4 composed of a main flow passage 2, a sub flow passage 3 and a merging portion 4 where the main flow passage 2 and the sub flow passage 3 are merged into one flow passage, and panel heaters 8 and 9 arranged at the positions that the inside of the sub flow passage 3 can be heated. The sub flow passage 3 and the merging portion 4 are subjected to hydrophobic treatment. Water and air are supplied respectively to the main flow passage 2 and the sub flow passage 3.
