    摘要： PROBLEM TO BE SOLVED: To provide a liquid feeding device with which an arbitrary liquid is quantified and fed with high accuracy.SOLUTION: A liquid feeding device has: a branching part where a fluid is branched into a main channel for feeding the fluid from the upstream side to the downstream side, and a first channel branching from the main channel; a narrow channel provided on another end of the first channel different from the branching part and having a smaller cross section than that of the first channel; and a liquid feeding mechanism to feed the fluid into the main channel and the first channel. The narrow channel suppresses a leakage of the fluid, which is fed from the main channel side into the first channel side at the branching part by the liquid feeding mechanism, from the first channel. By filling the inside of the first channel having a first volume with the fluid, the fluid is quantified according to the first volume, and the quantified fluid is fed to the main channel.
