A liquid moving apparatus comprising: a container having a holding chamber enclosed by first and second end walls facing against each other and side walls connecting the first and second end walls; a polarized or conductive first liquid filled in the holding chamber; a second liquid which does not mix with the first liquid, being filled in the holding chamber; first and second electrodes for applying an electric field to the first liquid; and voltage application means for applying voltage between the first electrode and the second electrode, wherein the first and second electrodes are placed along a virtual axis extending in the direction parallel to the first and second end walls, which is the direction orthogonal to the side walls; the second electrode is provided on the internal surface of the first end wall and the internal surface of the second end wall, which face the holding chamber, and includes multiple second electrode bodies in the direction of the extension of the virtual axis; the voltage application means is configured to apply a voltage selectively to each of the second electrode bodies, to bring the first liquid in contact with both of the first and second end walls and move the entire first liquid surrounded by the second liquid along the virtual axis; the electrode bodies at the both sides among the electrode bodies are placed at a position allowing the contact with the both sides of the first liquid; characterized in that the second electrode bodies include multiple electrode bodies having at least three sections (4002, 4004, 4006) in the direction orthogonal to the direction of the extension of the virtual axis. a container having a holding chamber enclosed by first and second end walls facing against each other and side walls connecting the first and second end walls; a polarized or conductive first liquid filled in the holding chamber; a second liquid which does not mix with the first liquid, being filled in the holding chamber; first and second electrodes for applying an electric field to the first liquid; and voltage application means for applying voltage between the first electrode and the second electrode, wherein the first and second electrodes are placed along a virtual axis extending in the direction parallel to the first and second end walls, which is the direction orthogonal to the side walls; the second electrode is provided on the internal surface of the first end wall and the internal surface of the second end wall, which face the holding chamber, and includes multiple second electrode bodies in the direction of the extension of the virtual axis; the voltage application means is configured to apply a voltage selectively to each of the second electrode bodies, to bring the first liquid in contact with both of the first and second end walls and move the entire first liquid surrounded by the second liquid along the virtual axis; the electrode bodies at the both sides among the electrode bodies are placed at a position allowing the contact with the both sides of the first liquid; characterized in that the second electrode bodies include multiple electrode bodies having at least three sections (4002, 4004, 4006) in the direction orthogonal to the direction of the extension of the virtual axis.
