To provide a microfluidic device including a fluidic pumping system that is easy to manufacture and capable of effectively pumping without depending on electric characteristics of solvents.

Provided is the microfluidic device (10) including the fluidic pumping system (30) for carrying the fluid through the device. The fluidic pumping system (30) includes a fluid-carrying channel (22) formed in the device (10), a plurality of acoustic pumping elements (32) arranged along the fluid-carrying channel (22), wherein the acoustic pumping elements (32) are configured to form an acoustic wave focused within the channel (22), and a controller (200) in electrical communication with the plurality of acoustic pumping elements (32), the controller (200) being configured to activate the acoustic pumping elements (32) in such a manner as to cause the acoustic wave to move along the channel (22) to move the fluid through the channel (22).
