Abstract

PURPOSE: To remove noise from a power source circuit without using any noise removing capacitor to be inserted between the power source circuit and an earthed circuit by using a ferroelectric substance for the first insulating layer.
CONSTITUTION: This circuit board device is constituted of the first conductive layer 1, first insulating layer 2, second conductive layer 3, second insulating layer 4, third conductive layer 5, fourth conductive layer 6, third insulating layer 7, via holes 8, through holes 9, and insulating spaces 10. A ferroelectric substance is used for forming the first insulating layer 2 formed between the first conductive layer 1 forming an earthing circuit and the second conductive layer 3 forming a power supplying circuit. As a result, such a state that a capacitor is inserted between the circuits 3 and 1 from the view point of the distributed constant is set up and a fault to a signal circuit can be prevented by removing the noise superimposed upon the power supplying circuit 3 over the entire front surface of this circuit board device. Therefore, the noise of the power supplying circuit can be removed without using any capacitor to be inserted between the power supplying circuit and earthing circuit.
