Fabrication method of printed circuit board and printed circuit board machining apparatus

A method for fabricating a printed circuit board, the method comprising:

• a resist layer forming operation of forming a resist layer on a surface of a printed circuit board, the printed circuit board having a conductor layer as an inner layer and the surface of the printed circuit board being an insulating layer;
• a recess forming operation of forming recesses having a depth not connected to the conductor layer from a surface of the resist layer at a first position and a second position set in advance by irradiating a second laser beam to the first and second positions;
• a hole forming operation of forming a hole reaching to the conductor layer from the surface of the resist layer at the first position by irradiating a first laser beam or the second laser beam from a surface side of the resist layer;
• a conductor filling operation of forming a conductor pattern by filling a conductive material into the hole and the recesses;
• and
• a resist layer removing operation of removing the resist layer such that portions of the conductor pattern project out of the surface of the insulating layer.
