Abstract
A circuit pattern of a power line and a circuit pattern of a signal line are disposed in a first layer of a laminated circuit board device, a circuit pattern of the signal line to be protected is disposed in a second layer, and a circuit pattern of a power line is disposed in a third layer. The shapes of the first circuit pattern of the power line of the first layer and the second circuit pattern of the power line of the third layer are substantially matched with each other with respect to a portion of the second layer facing the circuit pattern of the signal line. The direction of the current of the first circuit pattern coincides with the direction of the current of the second circuit pattern.
