A thermal cycler is provided that may be used as a nucleic acid amplification apparatus. The cycler has at least three temperature zones that can be set at different temperatures, the temperature zones including a first temperature zone, an intermediate zone, and a second temperature zone. The cycler has a channel including a plurality of forward subchannels and a plurality of backward subchannels, with the forward subchannels being different from the backward subchannels in terms of cross-sectional area in the intermediate zone. The channel is configured to continuously flow a fluid alternately through one of the forward subchannels and one of the backward subchannels, so that the fluid travels repeatedly between the first temperature zone and the second temperature zone via the intermediate zone, whereby the fluid is thermally cycled while the fluid flows through the channel.
