Abstract
In a printed wiring board, a first inner layer wiring line is formed on one surface of a wiring line formation layer, a resin film made of electric insulation resin is formed on an area other than the first inner layer wiring line formed on the wiring line formation layer. The resin film and the first inner layer wiring line have the same plane surface. A second wiring line is formed on the resin film, and the second wiring line is thinner in thickness than the first inner layer wiring line. A limit of error in thickness of the resin film and the first inner layer wiring line is within 10% of the thickness of each of the resin film and the first inner layer wiring line.
