Abstract: The present disclosure relates to a layered structure of a multi-layer PCB, and more particularly, to a structure of a high-power multi-layer PCB which can use a high current by efficiently dissipating heat generated from the inside of the multi-layered PCB and heat generated from a power semiconductor module package mounted on the PCB, and a production method thereof. The multi-layer PCB includes: a conductive plate having a plurality of heat poles protruding from at least one of a top surface and a bottom surface thereof; PCBs which are disposed on the top surface and the bottom surface of the conductive plate, and have a plurality of penetrating holes formed therethrough to allow the heat poles of the conductive plate to be inserted thereinto; and an insulation layer which is attached between the conductive plate and the PCBs in order to electrically insulate.
