Abstract
A liquid dispensing apparatus is provided which makes it possible to correctly and easily detect a dispensing operation judgment failure with high accuracy without particularly using a complicated detection mechanism or means. The liquid dispensing apparatus includes a nozzle which sucks a solution in a cassette and dispenses the sucked solution into another cassette; and a cassette holder which holds the another cassette, and the nozzle is used as a first electrode and the cassette holder as a second electrode. Further, the liquid dispensing apparatus has measurement means for measuring a capacitance between the first and second electrodes during a solution dispensing operation.
