Disclosed herein is a reaction container plate which prevents the entry of foreign matter from the outside and the pollution of an outside environment. A reaction container plate (1) includes a sealed reaction container (5), a reaction container channel (15) connected to the reaction container (5), a sealed container (17) provided separately from the reaction container (5), a sealed container channel (17a) connected to the sealed container (17), a syringe (33) for sending a liquid, a switching valve (47) for connecting the syringe (33) to the introduction channel (15) or the sealed container channel (17a), and a sealed container air vent channel (17b) of which one end is connected to the sealed container (17). When the syringe (33) is connected to the sealed container (17) via the switching valve (47) to inject a liquid contained in the syringe (33) into the sealed container (17) and to suck a liquid contained in the sealed container (17) into the syringe (33), a gas contained in the sealed container (17) is moved between the sealed container (17) and the sealed container air vent channel (17b).
