In an electroosmosis pump (10A), a bubble separation member (40) is provided at an exit side chamber (28) so as to be separated from an exit side electrode (20), a gas vent member (42) is provided at that side section of a pump container (12) which is near the exit side electrode (20), and a gas vent member (44) is provided at that side section of the pump container (12) which is near an entrance side electrode (18). A self-filling mechanism (50) is placed in an entrance side chamber (26), and the self-filling mechanism (50) is composed of a liquid drawing member (52) in contact with an electroosmosis material (16) via the entrance side electrode (18), and of an air vent path (56) formed between a member (54) surrounding a side section of the liquid drawing member (52) and the inner wall of the pump container (12).
