There is provided an apparatus for detecting a nucleic acid amplification product in real time, which is capable of effectively excluding or reducing apparatus error factors without using a second fluorescence signal used for correction. A plurality of wellsA are given with temperature cycles and fluorescence strength from a nucleic acid amplification product is detected in real time in each wellA. A fluorescence measurement value [DNA]raw obtained from the wellA and a fluorescence measurement value [DNA]bg obtained from a connection wall near the wellA are detected, and the fluorescence measurement value [DNA]bg is subtracted from the fluorescence measurement value [DNA]raw to determine fluorescence strength [DNA]real of the wellA.
