Abstract
A flexible wiring board includes a printed conductive circuit layer formed on an insulating film, a metallic layer formed on thed printed conductive circuit layer, and an insulating layer formed on the metallic layer. A method of making a flexible wiring board includes the steps of forming a conductive circuit layer by screen printing a wiring pattern using a conductive paste, baking the printed wiring pattern, and forming a metallic layer on the printed conductive circuit layer by a plating method.
