Abstract
A circuit board, including a first dielectric material, a second dielectric material, a third dielectric material, a fourth dielectric material, a first external circuit layer, a second external circuit layer, a conductive structure, a first conductive via, and multiple second conductive vias, is provided. The first conductive via at least passes through the first dielectric material and the fourth dielectric material, and is electrically connected to the first external circuit layer and the second external circuit layer to define a signal path. The second conductive vias pass through the first dielectric material, the second dielectric material, the third dielectric material, and a part of the conductive structure, and surround the first conductive via. The second conductive vias are electrically connected to the first external circuit layer, the conductive structure, and the second external circuit layer to define a ground path, and the ground path surrounds the signal path.
