The disclosed liquid-delivery device (20) has a channel (11), an opening (16) of which is sealed by a sealing film (17), and delivers a liquid to a test chip (10). Said liquid-delivery device (20) is provided with: a nozzle (22) that discharges or suctions a liquid into the channel (11); a reciprocal movement means (30) that moves the nozzle (22) closer to or further away from the test chip (10), with the tip of the nozzle (22) pointed towards the aforementioned opening (16); and a control means (50) that controls the reciprocal movement means (30). The outside diameter of the nozzle (22) decreases towards the tip thereof. Each time the control means (50) inserts the nozzle (22) into the channel (11) via the opening (16), the control means inserts the tip of the nozzle (22) further past the opening (16) than the previous time. |
