The invention relates to a circuit board, particularly for a power-electronic module, comprising an electrically-conductive substrate which consists, at least partially and preferably entirely, of aluminium and/or an aluminium alloy. On at least one surface of the electrically-conductive substrate, at least one conductor surface is arranged in the form of an electrically-conductive layer applied preferably using a printing method and more preferably using a screen-printing method, said conductor surface being in direct electrical contact with the electrically-conductive substrate.
