ABSTRACT:
A printed board has at least two conductor layers including a power supply layer and a ground layer, and a spiral coil inductor disposed in opposite ones of the conductor layers. The spiral coil inductor has a terminal connected to a power supply line of the power supply layer, and another terminal connected to a device power terminal disposed on one of the conductor layers and to be connected to a power supply terminal of a circuit device and a terminal of a decoupling capacitor. A device ground terminal is disposed on one of the conductor layers and to be connected to a ground terminal of the circuit device and another terminal of the decoupling capacitor, the device ground terminal being connected to a ground line of the ground layer.
