PROBLEM TO BE SOLVED: To facilitate the formation of a circuit pattern on a board without necessitating so many manufacturing processes. SOLUTION: The printed circuit board manufacturing apparatus 1 comprises a mounting table 18 for mounting a board 2 thereon, a mixing container 8 for producing a mixed fluid 3a by melting an organic copper compound 3 into a supercritical carbon dioxide 7a, a head 5 arranged opposite to the board 2 on the mounting table 18 for ejecting the mixed fluid 3a toward the surface of the board 2, a travelling mechanism 14 for moving the head 5 along the wiring route for the formation of the pattern 3c in the board 2 on the mounting table 18, and a laser source 9 for heating the mixed fluid 3a by laser irradiation just before the landing of the mixed fluid 3a blowing out from the travelling head 5 on the surface of the board 2 for the fusion of the copper component of the mixed fluid 3a onto the surface of the board 2 for the formation of the circuit pattern 3c.
