Patent ID: 8912802

Claim:
A component-embedded circuit substrate, comprising: a circuit substrate; and a first capacitor and a second capacitor embedded in the circuit substrate, the first capacitor and the second capacitor being connected in parallel by first wiring lines, wherein a capacitance of the second capacitor is greater than a capacitance of the first capacitor, wherein a pair of inspection electrodes are formed on a first main surface of the circuit substrate, wherein the inspection electrodes are respectively connected to terminal electrodes of the first capacitor through second wiring lines, wherein each of the first wiring lines includes a pattern for connecting the first and second capacitors together, said pattern being formed on a second main surface of the circuit substrate or formed in an inner layer further towards the second main surface than the first and second capacitors, and each of the first wiring lines further includes first via conductors that respectively connects said pattern to a corresponding one of the terminal electrodes of the first capacitor and to a corresponding one of terminal electrodes of the second capacitor, wherein each of the second wiring lines includes a second via conductor that extends from a corresponding one of the terminal electrodes of the first capacitor to the first main surface, and wherein at each of the terminal electrodes of the first capacitor, a position at which the first via conductor is connected to the terminal electrode is different from a position at which the second via conductor is connected to the terminal electrode.
