1. A capacitor-mounted wiring board comprising:

  • a plurality of wiring layers each patterned in a required shape;

    the plurality of wiring layers being stacked with insulating layers interposed therebetween and connected to each other via conductors formed to pierce the insulating layers in a direction of thickness; and

    a capacitor surface-mounted on at least one of the same surface on which a semiconductor element, an electronic component, or the like, is to be mounted;

    the capacitor being mounted such that the capacitor is electrically connected to a wiring layer used as any one of a power supply line and a ground line, and in a vicinity of the wiring layer among the plurality of wiring layers, and such that, when a current is passed through the capacitor, a direction of the current and a direction of a current flowing through the wiring layer are reversed.
