Abstract: The invention proposes a device for active and/or passive supply of fluids comprising a microfluidic component with an inlet and optionally an outlet, a strip conductor which is electrically conductingly connected to the microfluidic component, and a carrier on which the microfluidic component is fixed. In order to provide a simple and inexpensive fluidic connection of the microfluidic component, in accordance with the invention, the carrier is formed by a board comprising the strip conductor, which has one passage channel which is flush with the inlet and optionally one which is flush with the outlet of the microfluidic component, and wherein a feed line for the inlet or an outlet line for the outlet is formed by a channel opening into the passage channel, wherein the channel is formed on the side of the board facing away from the microfluidic component by one groove-like recess each. The microfluidic component can e.g.
