Beschreibung
Zusammenfassung:	Provided is a microchip which is capable of determining the quantity of the liquid in the chip and dividing the liquid, and has a relatively simple flow passage structure. In the microchip liquid supply system, a portion of the liquid in an upstream passage (r11) among the liquid injected into a first flow passage (r1) is supplied from a liquid discharge passage (r3) by operating a suction pump connected to a liquid supply passage in such a state that an air vent hole (111) is closed. Thereafter, the suction pump is operated with the air vent hole (111) closed, whereby a portion of the liquid in a quantity determination passage (r12) among the liquid injected into the first flow passage (r1) is supplied from a liquid supply passage (r5).
