PROBLEM TO BE SOLVED: To provide a transdermal transport device capable of the accurate insertion of needles without pain and capable of the programmable control. SOLUTION: The transdermal transport device 10 includes a reservoir 46 for holding a substance including a specific component, and an array of needles 12. The array of needles 12 makes it easy to transport the substance into the reservoir 46 through the needles 12 and to transport the substance from the reservoir 46 to the outside through the needles 12 because the needles have bores liquid-communicating with the reservoir 46. The transport device further includes a first actuator 24 to drives the array of needles into the living body, and a second actuator 38 to transport the substance between the reservoir 46 and a target through the needles 12 by means of the pumping action. The first actuator 24 is a reversible actuator to act in the reverse direction, so that the needles can be withdrawn from the living body. COPYRIGHT: (C)2010,JPO&INPIT
