Nucleic acid analysis apparatus includes a plurality of temperature adjustment apparatuses, a rotating mechanism, a delivery base and an ejection base, a delivery drive mechanism, an ejection drive mechanism, and a detection apparatus. The rotating mechanism can include a rotating shaft and a plurality of pressing portions that rotate around the rotating shaft. The reaction plate assembly can move over the temperature adjustment apparatuses along the circumferential direction in a state of being pressed onto the temperature adjustment apparatuses by the pressing portions. The delivery drive mechanism can cause the reaction plate assembly to be moved radially inward and delivered between the pressing portions and temperature adjustment apparatuses. The ejection drive mechanism can cause the reaction plate assembly to be moved radially outward and ejected from between the pressing portions and temperature adjustment apparatuses onto the ejection base. Reaction plates, reaction plate assemblies, and nucleic acid analysis apparatuses are provided.
