PROBLEM TO BE SOLVED: To provide a laminated circuit board and a method for detecting the same, capable of easily detecting the positional deviation of an internal wiring conductor without cutting the board, even after baking. SOLUTION: In the method for detecting the positional deviation of the internal wiring conductor 2 after manufacturing a circuit board 10 formed with the internal wiring conductor 2, the circuit board 10 comprises a central via conductor 7, independently of the conductor 2 through at least one dielectric layer from the surface of the board, lands 11b to 11d connected to an end face of the via conductor in any of the dielectric layers, and a plurality of detection via conductors 8a to 8d, reaching the dielectric layers, formed with at least the lands from the surface of the board and surrounding the conductor 7 separated by an interval from the lands. |
