A microchip having an inlet opening (14) for collecting a sample liquid; at least one capillary cavity (4) capable of collecting a specific amount of the sample liquid through the inlet opening (14) by using capillary force; and a holding chamber (5) communicating with the capillary cavity (4) and receiving the sample liquid in the capillary cavity (4) transferred by centrifugal force generated by rotation about an axis. The capillary cavity (4) interconnecting the inlet opening(14) and the holding chamber (5) has, in one side face of the capillary cavity (4), cavities (15, 16) not generating capillary force and communicating with the atmosphere, and this prevents mixing of air bubbles into the capillary cavity (4). |
