Abstract: In a circuit board, a printed board includes an insulating base and a plurality of conductors disposed in layers in the insulating base. The conductors include a signal line electrically connected to an electronic component; and a potential fixed layer fixed to a predetermined potential and arranged to face the signal line across the insulating base in a thickness direction of the printed board. The potential fixed layer has a facing surface facing the signal line, and is provided with a high magnetic film having a magnetic permeability higher than that of the at least one potential fixed layer on the facing surface. The high magnetic film is disposed to overlap the signal line in the thickness direction. The signal line includes a facing line that faces the high magnetic film across the insulating base in the thickness direction.

Abstract: An electronic device includes first, second, and third circuit components, a reinforcing member, and electrical connectors. The second circuit component includes a surface on which the first circuit component mounts. The second circuit component is electrically connected to the first circuit component. The reinforcing member is in contact with the first circuit component and the surface of the second circuit component, and reinforces a connection between the first and second circuit components. The third circuit component has a mounting surface on which the second circuit component mounts, and is electrically connected the second circuit component. The electrical connectors include at least one electrical connecting portion establishing an electrical connection between the second circuit component and the third circuit component. At least one section of each of the electrical connectors is outside a member facing portion facing the reinforcing member.
