摘要:
A wiring board includes: a first wiring layer; a first insulating layer formed on the first wiring layer and including a reinforcing material therein, the first insulating layer having a first opening; a contact layer formed on the first insulating layer and having a second opening communicated with the first opening; and a second wiring layer comprising a second via and a second wiring pattern connected to the second via. The second wiring pattern is formed on the contact layer, and the second via is filled in the first and second openings. An adhesion property between the contact layer and the second wiring pattern is higher than that between the first insulating layer and the second wiring pattern, and a thickness of the contact layer is smaller than that of the first insulating layer.

An interference wave signal frequency is highly accurate and the interference wave signal is surely removed. A controller of an interference wave signal remover detects the interference wave signal based on a frequency scanning result by an entire-range frequency scanner, and sets a notch filter to attenuate the interference wave signal frequency. A local scan frequency band BWfL of a local frequency scanner is set by having the interference wave signal frequency as its central frequency, and local scan frequencies BINL are set so that frequency bands overlap with each other between adjacent frequency BINA. The local frequency scanner frequency-scans input signals to the notch filter. The controller calculates a frequency error δf of the interference wave signal frequency from the local frequency scanner, corrects the interference wave signal frequency which is from the entire-range frequency scanner by the frequency error δf, and updates the setting of the notch filter.
