Abstract

A printed wiring board which has a conductor circuit (12) on an insulating substrate (10) and a surface insulating layer (14) formed on the surface of the substrate (10) including the surface of the conductor circuit (12). Part of the conductor circuit (12) has an exposed conductor section (120) having an exposed surface, and a surface insulating layer (140) around the conductor section (120) forms a recessed section at the same level of the surface of the conductor section (120) or lower than the surface. It is preferable to form a black or white solder resist layer on the surface insulating layer.
