A thermal cycler includes a holder that holds a biotip filled with a reaction mixture and liquid having a smaller specific gravity than the reaction mixture and being immiscible with the reaction mixture, the biotip including a channel in which the reaction mixture moves, a heating unit that heats a first portion of the channel when the biotip is in the holder, and a driving unit that disposes the holder and the heating unit by making a switch between a first disposition and a second disposition, the first disposition being such that the first portion is in a lowest part of the channel with respect to a gravitational force direction when the biotip is in the holder, the second disposition being such that a second portion that is a different portion from the first portion relative to a moving direction of the reaction mixture is in the lowest part of the channel with respect to the gravitational force direction when the biotip is in the holder. |
