To provide a sample analyzing chip low in cost constituted to send a liquid to the wells formed on the chip to perform reaction, simplifying a liquid sending method and eliminating the irregularity of the liquid quantities in the respective wells.

In the sample analyzing chip constituted by providing a large number of the wells 102, the flow channels connected to the respective wells and an injection port for injecting a solution in the flow channels to a base material 101 and distributing the solution to the wells by rotating the base material, the flow channels have the first liquid sump parts 108 communicating with the injection port and provided on the side of the center of rotation of the wells, the second liquid sump parts 109 communicating with the first liquid sump parts through communication flow channels and corresponding to the respective wells, and the branch channels 105 allowing the second liquid sump parts to communicate with the wells.
