PROBLEM TO BE SOLVED: To facilitate piping work in an external pipe connector without disposing the pipe connector outside of a liquid feeder, the pipe connector for connecting an external module to a pump head outlet flow path of the liquid feeder. SOLUTION: This liquid feeder includes the pump head outlet flow path provided on a piping panel of the liquid feeder for connecting a pump head outlet to the external pipe connector. A coil-shaped pipe and a line filter for solid matter removal are provided on the flow path. The coil-shaped pipe is a metallic pipe which is helically wound to form a coil spring that expands and contracts in parallel to a panel plane. The line filter, whose downstream end serves as the pipe connector, is connected to the downstream side of the coil-shaped pipe on the flow path and is movable in the panel plane until the pipe connector is pulled out from within the panel to the exterior thereof by the expansion and contraction of the coil-shaped pipe. An enclosure for enclosing the piping panel is provided with a hole that guides the pipe connector from within the panel to the exterior thereof in moving the line filter.
