To provide a liquid measuring vessel capable of accurately measuring a plurality of kinds of liquids.
The liquid measuring device includes a liquid ejection mechanism 12 that sequentially ejects a plurality of kinds of liquids, a measuring vessel 14 and a control section 16. The measuring vessel 14 has a vessel body 30 and a cap unit 32 attached to the top of the vessel body 30. The vessel body 30 is divided into a plurality of regions in vertical directions correlated to one or more liquids, in which the more a target input amount of liquid is reduced the more the cross sectional area is reduced. The control section 16 determines a liquid level of the vessel body 30 based on electric signals from a plurality of electrode pairs 42 attached at the cap unit 32 and controls the drive of the liquid ejection mechanism 12 in accordance with the determination result.
