PROBLEM TO BE SOLVED: To provide a printed circuit board and a method for manufacturing the same capable of easily forming a printed circuit board provided with a migration occurrence suppressing effect in the printed circuit board provided with a thinned conductor pattern. SOLUTION: In the printed circuit board 10 provided with the conductor pattern 12 on the surface of an insulation substrate 11, the conductor pattern 12 is provided with a first conductor layer 13 provided on the surface of the insulation substrate 11, and a second conductor layer 15 provided on the surface side of the first conductor layer 13 and constituting the outermost layer of the conductor pattern 12. In the outer surface of the conductor pattern 12, at least on the side surface of the first conductor layer 13, a protection layer 16 thinner than the thickness B of the second conductor layer 15 in a laminating direction is formed.
