Abstract
A wiring board includes a first interconnect structure including a first interconnect layer and a first insulating layer, and a second interconnect structure, including a second interconnect layer and a second insulating layer, and disposed on the first interconnect structure. Interconnect width and spacing of the second interconnect layer are smaller than those of the first interconnect layer. The first insulating layer covers a side surface of the first interconnect layer and exposes an upper surface of the first interconnect layer. The second insulating layer covers the upper surface of the first interconnect layer and an upper surface of the first insulating layer. The first insulating layer and the second insulating layer include a filler. An average grain diameter and a maximum grain diameter of the filler included in the second insulating layer are smaller than those of the filler included in the first insulating layer.
