A liquid transport apparatus includes a tube for constituting a flow channel 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 catheter for injecting the liquid into a living body, a first electrode that is provided further toward the downstream side than a region pushed by the plural fingers and is made to come into contact with the liquid, a second electrode made to come into contact with the living body, and a determination unit that determines that the catheter comes off the living body on the basis of the impedance between the first electrode and the second electrode.
