1. A sample analysis chip comprising:
a base; a plurality of wells that are disposed on the base; and a channel that is disposed on the base and is connected to the plurality of wells, the channel comprising
a main channel portion that is disposed at a position closer to a rotation center than the plurality of wells on the base and is supplied with a solution which is to be dispensed to each of the plurality of wells, the main channel portion having ridges positioned near the rotation center of the base and valleys positioned near the wells relative to the ridges, the main channel portion configured to meander, and the wells being in communication with the valleys,a first buffer portion that is in communication with a first end of the main channel portion and is capable of accommodating a portion of the solution,a second buffer portion that is in communication with a second end of the main channel portion and is capable of accommodating a portion of the solution,a solution supply channel having a first end of which is in communication with the first buffer portion and a second end of which is opened to the atmosphere, andan air vent channel having a first end of which is in communication with the second buffer portion and a second end of which is opened to the atmosphere. |
