Abstract
A wiring board has a first resin insulation layer, a first conductive pattern formed on the first resin insulation layer, a second resin insulation layer formed on the first conductive pattern and having an opening portion exposing at least a portion of the first conductive pattern, a second conductive pattern formed on the second resin insulation layer, and a via conductor formed in the opening portion of the second resin insulation layer and electrically connecting the first conductive pattern and the second conductive pattern. The via conductor has a side surface extending between the first conductive pattern and the second conductive pattern and a bent portion where an inclination of the side surface of the via conductor changes in a depth direction of the via conductor.
