Claim 16:
17. A printed circuit board comprising:
a first insulating layer having a first surface and a second surface opposing each other in a stacking direction;
a second insulating layer disposed on the first surface of the first insulating layer;
a via pad at least partially embedded in the first insulating layer;
a fine circuit unit embedded in the first insulating layer, exposed to the first surface of the first insulating layer, and disposed adjacent to a side of the via pad in a width direction perpendicular to the stacking direction;
a first via layer embedded in the first insulating layer, exposed to the second surface of the first insulating layer, and connected to one side of the via pad; and
a second via layer embedded in the second insulating layer and connected to an opposing side of the via pad,
wherein the fine circuit unit is not in direct contact with any conductive element, and each of the first and second insulating layers is a single layer.
