The invention relates to a printed circuit board comprising conductor tracks (2) formed on one side of a substrate (1), wherein the substrate (1) can be connected integrally to a covering to protect the conductor tracks (2) on a contact surface (2). The substrate comprises a step (3), which forms a barrier with respect to an additive for promoting the integral connection, in order to prevent wetting of the conductor tracks with the additive. The invention further relates to a sensor comprising such a printed circuit board, for example for use in a fuel level measuring system of a vehicle. 本发明涉及种印刷电路板，该印刷电路板具有在基板(1)的侧上形成的导体轨道(2)，其中，该基板(1)能够在接触面(2)处粘合性地结合到用于保护这些导体轨道(2)的覆盖件上。在这种情况下，该基板包括台阶(3)，该台阶对于用于促进粘合性结合的辅助材料形成屏障，以防止该辅助材料对这些导体轨道的任何润湿。此外，本发明涉及种具有这种印刷电路板的传感器，例如在车辆的燃料填充液位测量系统中使用。
