    Abstract: A printed circuit board includes: an insulating member; a first wiring layer disposed in the insulating member, and including first and second pattern layers spaced apart from each other based on a thickness direction of the printed circuit board; and a second wiring layer disposed in the insulating member, and spaced apart from the first pattern layer over the first pattern layer based on the thickness direction. Based on the thickness direction, an insulation distance between the first pattern layer and the second pattern layer is smaller than an insulation distance between the first pattern layer and the second wiring layer, and each of the first and second pattern layers is thinner than the second wiring layer.

    Abstract: A printed circuit board includes a substrate portion including a first insulating layer, and a first wiring layer disposed on or in the first insulating layer, and a connection structure disposed on or in the substrate portion, the connection structure including a plurality of first dielectric layers, first and second metal layers respectively disposed on the plurality of first dielectric layers, a second insulating layer disposed on the plurality of first dielectric layers, and a second wiring layer disposed on the second insulating layer. Each of the plurality of first dielectric layers includes an organic material. A distance between the first metal layer and the second metal layer is less than a distance between the first metal layer and the second wiring layer.
