PROBLEM TO BE SOLVED: To provide a printed wiring board that is equipped with interconnections, whose routing is minimally carried out, which is suitable for high-density mounting, and excellent noise-resistant properties, and to provide its manufacturing method. SOLUTION: The printed circuit board with a base board of resin is provided with through-holes whose inner walls are covered with conductors and pads to which the conductor terminals of parts mounted on the surface of the printed wiring board are connected. The pad is configured in such a manner that the through-hole is arranged within its region, the through-hole is filled up with a prescribed filler, and the end of the filler located at the surface of the printed wiring board is covered with the pad of a conductor.
