A microvolume liquid dispensing device capable of automatically dispensing a predetermined volume of a microvolume liquid placed from the outside. Because one surface of a main flow path (13) is gradually varied from a hydrophobic nature to a hydrophilic nature, a microvolume liquid (A) placed in the main flow path (13) can be automatically conveyed. One surface of a side flow path (14) is of a hydrophilic nature, so that a portion of the microvolume liquid (A) can be automatically dispensed to the side flow path (14).
