PROBLEM TO BE SOLVED: To provide a manufacturing method for an easily-manufacturable and inexpensive printed wiring board that is excellent in productivity and solder joint performance, a protection sheet applied to the manufacturing method, and a printed wiring board provided with the protection sheet. SOLUTION: The manufacturing method is used for manufacturing the printed wiring board 10 which has a laminated structure formed by laminating a conductor layer 11 and an insulating resin 12 and in which a solder joint terminal 11A is formed at the conductor layer 11 arranged on the outermost layer. A solder resist 13 is formed on the conductor layer 11 arranged on the outermost layer so as to expose the solder joint terminal 11A and to surround the solder joint terminal 11A. The protection sheet 15 is thermally press-bonded or arranged by a heat-roller lamination method on the solder resist 13 so as to cover at least the solder joint terminal 11A.
