A printed wiring board includes a mounting portion 60 on which a dual core processor 80 including two processor cores 81A and 81B in a single chip can be mounted, power supply lines 12A and 12B, ground lines 11A and 11B, and a first layered capacitor 40A and a second layered capacitor 40B which are independently provided for each of the processor cores 81A and 81B, respectively. Accordingly, even when the electric potentials of the processor cores 81A and 81B instantaneously drop, an instantaneous drop of the electric potential can be suppressed by the action of the layered capacitors 40A and 40B corresponding to the processor cores 81A and 81B, respectively. In addition, even when the voltage of one of the processor cores varies, the variation in the voltage does not affect the other processor core, and thus malfunctioning does not occur. |
