Abstract: A manufacturing method of the circuit board includes the following. The third substrate has an opening and includes a first, a second and a third dielectric layers. The opening penetrates the first and the second dielectric layers, and the opening is fully filled with the third dielectric layer. The first, the second and the third substrates are press-fitted so that the second substrate is located between the first and the third substrates. Multiple conductive structures are formed so that the first, the second and the third substrates are electrically connected through the conductive structures to define a ground path. A conductive via structure is formed to penetrate the first substrate, the second substrate, and the third dielectric layer of the third substrate. The conductive via structure is electrically connected to the first and the third substrates to define a signal path. The ground path surrounds the signal path.
