Abstract
A liquid transport apparatus includes a tube for transporting a liquid, plural fingers that push and block the tube, a cam that pushes the fingers in sequence so as to squeeze the tube to transport the liquid, a first electrode and a second electrode that are provided at the tube located further toward the downstream side than a region pushed by the plural fingers, and a determination unit that determines the presence/absence of a bubble on the basis of the impedance between the first electrode and the second electrode.
