Zusammenfassung:The invention relates to a capacitor-embedded and resistor-embedded carrier plate and a manufacturing method thereof, and the method comprises the steps: S1, manufacturing a parallel-plate capacitor through employing an inner-layer capacitor embedding technology, the parallel-plate capacitor at least comprises a dielectric layer, and the two sides of the dielectric layer are respectively provided with at least two copper foils; s2, selecting a gap between any two copper foils on the same side of the dielectric layer as a buried resistor position, and plating copper at the buried resistor position; s3, preparing a resistor material at the copper plating position, wherein the resistor material is respectively in contact with the two copper foils adjacent to the buried resistor position to form a resistor; and S4, carrying out screen printing of solder resist ink for protection on the resistor. According to the manufacturing method, the resistor and the capacitor are manufactured on the same layer, and the space
