Abstract

A package substrate includes interlayer insulating layers including outermost and inner-layer layers, conductor layers including an outermost layer, a first layer between the outermost and inner-layer layers, and a second layer on which the inner-layer layer is formed, via conductors including first and second conductors through the outermost insulating layer, and skip via conductors through the outermost and inner-layer insulating layers to connect the outermost and second conductor layers. The outermost conductor layer includes first and second pads to mount first and second electronic components on the outermost insulating layer, the first conductors are positioned to connect the first conductor layer and first pads, the second conductors are positioned to connect the first conductor layer and second pads, and the first conductor layer has area on surface of the inner-layer insulating layer which is in range of 3 to 15% of area of the surface of the inner-layer insulating layer.
