    • PROBLEM TO BE SOLVED: To provide a printed circuit board and a method of manufacturing the same, and a via hole drilling apparatus. SOLUTION: The method of manufacturing the printed circuit board includes a step of forming a first circuit pattern including a reference mark and a land for a via on one surface of an insulating board; a step of forming an insulating layer on one surface of the insulating board; a step of forming a metal layer on the insulating layer; a step of opening a first window corresponding to the reference mark in the metal layer; and a step of irradiating one surface side with light through the other surface of the insulating board and recognizing the reference mark through the first window to form a via for electrically connecting the land for a via and the metal layer. In the formation of the via for electrically conducting circuit patterns of the printed circuit boards, short-circuiting among the circuits is prevented and disposal rates of boards due to eccentricity among the insulating layers are reduced, contributing to the reduction of costs.
