Abstract: The present disclosure discloses a printed circuit board, a method for manufacturing the same and an electronic device. The PCB includes: a core board assembly including a first core board and a second core board which are stacked together, wherein the second core board includes a metal layer formed on a side of the second core board oriented towards the first core board, and the first core board defines a through slot extending through the first core board; a radiator, disposed in the through slot; and a conductive adhering layer, disposed between the metal layer of the second core board and the radiator, wherein the conductive adhering layer is configured to electrically connect the radiator and the metal layer. The present disclosure connects the radiator directly with the metal layer. The implementation of the present disclosure may help cooling the metal layer to improve the cooling performance of the PCB.
