PROBLEM TO BE SOLVED: To provide a safety printed wiring board in which conductive parts are hardly oxidized and corroded, even if each layer constituting the printed wiring board is made thin, and to provide a method for manufacturing the same. SOLUTION: The printed wiring board comprises a substrate body 10 and a conductive pattern 14 formed a circuit on the substrate body 10. The substrate body 10 is made from an insulating material, such as polyethylene terephthalate, polyimide and liquid crystalline polymer. The conductive pattern 14 is formed of conductive members such as copper, and both rims 14a, 14a where an upper surface 14b and each side surface 14c, 14c cross, are formed in a R shape.
