ABSTRACT:
A liquid transport apparatus includes a flow passage which has a liquid discharge port and which includes a first area and a second area formed on an inner wall to make contact with a liquid, the second area being adjacent to the first area in a flow direction of the liquid and having liquid repellence higher than that of the first area. When the pressurized liquid is supplied to the flow passage toward the liquid discharge port, then the liquid is incapable of passing through the second area owing to the liquid repellence of the second area, and thus a gas stays in the second area in accordance therewith. The liquid transport apparatus further includes a liquid passage-permitting mechanism which selectively permits the pressurized liquid to pass through the second area. The apparatus is provided, wherein the high integration can be easily realized, and the flow passage is simply constructed.
