PROBLEM TO BE SOLVED: To provide a printed circuit board ensuring excellent reliability of connection between internal wall of through-hole and through-conductor thereof, and to provide a method of manufacturing the same. SOLUTION: The printed circuit board 21 comprises an insulated base material 5 including at least fiber 1 and resin 3, a through-hole 7 formed to the insulated base material 5, and a through-conductor 9 constituted of the metal phase formed to the through-conductor 7. In this printed circuit board 21, an alienating part A alienating the fiber 1 and resin 3 is opened to the through-hole 7, and a sealing conductor 11 is also formed to the alienating part A.
