PROBLEM TO BE SOLVED: To provide a printed wiring board free from short-circuiting even with a gap of a conductor circuit getting narrow. SOLUTION: The printed wiring board has a flat conductor circuit whose gap is narrower than a conductor width. A method of manufacturing the printed wiring board includes steps of: applying a liquefied resist to a metallic foil with a carrier layer; laminating a dry film resist including the same ingredients as those of the liquefied resist on the liquefied resist; exposing/developing the liquefied resist and the dry film resist to form a plated resist; depositing metal plating to serve as a conductor in an opening of the plated resist; and peeling the plated resist to form the conductor.
