Abstract
The liquid feeder includes a liquid feeding pipe having a liquid introduce port and a liquid discharge port, a housing container which holds liquid to be introduced from the liquid introduce port, a liquid feed mechanism which feeds the liquid in the liquid feeding pipe to the liquid discharge port, a gas introduce unit which introduces gas into the liquid feeding pipe, and a liquid level detection unit which detects an advancing liquid level of the liquid to be fed in the liquid feeding pipe. The gas introduce unit is connected to a branch part provided in the liquid feeding pipe on the upstream side of the liquid feed mechanism. The liquid level detection unit is provided on the downstream side of the branch part.
