摘要： The present disclosure relates to a printed circuit board include: a core layer including an inorganic insulating layer, a resin layer covering at least a portion of an external side surface of the inorganic insulating layer, and a second insulating layer covering at least a portion of a lower surface of each of the inorganic insulating layer and the resin layer and having an interlayer boundary with the resin layer; a first wiring layer disposed on an upper surface of the core layer; and a second wiring layer disposed on a lower surface of the core layer. The external side surface of the inorganic insulating layer is substantially perpendicular to at least one of the upper surface and the lower surface of the inorganic insulating, and a manufacturing method therefor.
