Abstract: The invention provides a reciprocal-flow-type nucleic acid amplification method performing thermal cycling by reciprocating a sample liquid between a denaturation temperature zone and an elongation-annealing temperature zone with a connected microchannel including at least a curved channel corresponding to the denaturation temperature zone, a curved channel corresponding to the elongation-annealing temperature zone, a linear or curved intermediate channel that connects the aforementioned curved channels, and a connector to connect to a liquid delivery mechanism for enabling movement of the sample liquid. The method includes moving the sample liquid in the channel by the liquid delivery mechanism that is open to atmospheric pressure when liquid delivery is stopped, and measuring a fluorescence intensity for each thermal cycle at a predetermined point on the channel corresponding to the denaturation temperature zone and at a predetermined point on the channel corresponding to the elongation-annealing temperature zone to perform real-time PCR.
