Abstract

See full text

A printed circuit board has: a first wiring pattern laid in a first layer such that, when a predetermined component is mounted in a predetermined mounting region, a first current path in an open ring shape leading from a first end to a second end is formed; a second wiring pattern laid in a second layer different from the first layer such that a second current path in an open ring shape leading from a third end to a fourth end is formed; a first conductive member formed between the second and third ends; and a second conductive member formed between the first and fourth ends. The first and second wiring patterns are so laid that, as seen in their respective plan views, the directions of the currents flowing across the first and second current paths, respectively, are opposite to each other.
