Abstract
An electrophoresis chip is formed of a pair of transparent base plates. A sample introduction flow path and a separation flow path crossing each other are formed on a surface of one of the base plates, and the other base plate is provided with a separation buffer waste, a separation buffer reservoir, a loading buffer reservoir, and a loading buffer waste, which are formed as through holes at positions corresponding to ends of the flow paths. Further, a sample reservoir for injecting a sample therein is formed as a through hole on the sample introduction flow path at a position different from that of the loading buffer reservoir. Electrodes are disposed at the separation buffer waste, the separation buffer reservoir, the loading buffer reservoir, and the loading buffer waste. The electrode is not disposed at the sample reservoir.
