Abstract
A flexible circuit board including a substrate having at least electrically conducting patterns and electrically insulating cover layers formed on both sides thereof. A number of apertures are formed along a line in a zone at which the board is to be curved. In this zone, areas between two successive apertures having conducting patterns on the front surface do not have conducting patterns on the back surface, and further, the cover layer is applied only to the surface of the areas on which conducting patterns are formed, while the opposite surface having no patterns formed thereon is absent the cover layer.
