Abstract
A wiring substrate includes a first build-up part including an insulating layer and a conductor layer, and a second build-up part including an insulating layer and a conductor layer. The minimum wiring width of wirings in the conductor layer of the first build-up part is smaller than the minimum wiring width of wirings in the conductor layer of the second build-up part. The minimum inter-wiring distance of the wirings in the first part is smaller than the minimum inter-wiring distance of the wirings in the second part. The first build-up part is formed such that the conductor layer includes a conductor pattern including a first metal layer, a second metal layer, and a third metal layer. The width of the first metal layer is larger than the width of the second metal layer. The width of the third metal layer is larger than the width of the first metal layer.
