A reaction processor is provided with a reaction processing vessel having a channel, a liquid feeding system, a temperature control system, and a fluorescence detector, and a CPU for controlling the liquid feeding system. When a sample moves from a low temperature region to a high temperature region, the CPU instructs the liquid feeding system to stop the sample when a predetermined first waiting time has passed from the time when the passage of the sample through a fluorescence detection region is detected by the fluorescence detector. When the sample moves from the high temperature region to the low temperature region, the CPU instructs the liquid feeding system to stop the sample when a predetermined second waiting time, which is set independently of the first waiting time, has passed from the time when the passage of the sample through the fluorescence detection region is detected by the fluorescence detector.
