Abstract: A thermal convection generating chip (1) includes a rotatory body (2), a thermal convection pathway (11) provided in the rotatory body (2), and a supply path (12A to 12C) that supplies a liquid to the thermal convection pathway (11). The supply path (12A to 12C) includes a liquid receiving section (121) that receives the liquid and a suction passage (122) that provides communication between the liquid receiving section (121) and the thermal convection pathway (11). The suction passage (122) has a first region (122a) extending between a midsection of the suction passage (122) and the thermal convection pathway (11), and a second region (122b) extending between the midsection and the liquid receiving section (121). The liquid in the first region (122a) is separated from the liquid in the second region (122b) through rotation of the rotatory body (2) to be supplied to the thermal convection pathway (11).
