The invention relates to a method for producing at least one circuit part on a substrate (20). Said method comprises the following steps: at least one granulate (54), which contains an electric conductor and which has a predefined geometric distribution, is deposited on the substrate (20) and the granulate (54) is heated and forms a permanent connection with the substrate (20) and forms at least one circuit part on the substrate (20). The invention also relates to a circuit board comprising at least one substrate, on which at least one circuit part is arranged, and to a device for producing at least one circuit part on a substrate (20).
