Provided in the present application are a resistor-buried circuit board and a processing method. A circuit board including a built-in resistor is obtained by forming a resistor-buried recess on a substrate and burying a resistor in the resistor-buried recess. By forming the resistor-buried recess, the high-precision control over the shape and the thickness of the buried resistor can be quite easily realized, the ultrahigh resistor burying precision is realized, and high-precision batch processing can also be implemented easily. In a resistor-buried layer, the resistor is built in the substrate, such that during a lamination process, the situation where cracks and large amounts of deformation occur after lamination due to the unevenness of the resistor-buried layer is avoided, thereby improving the reliability and yield of the circuit board.
