PURPOSE: A printed circuit board equipped with a metal core is provided to omit configuration for electrical connection between printed circuit boards by forming a first circuit area and a second circuit area on one printed circuit board. CONSTITUTION: An exposing unit is formed by exposing both ends of a metal core(16) and the surface between both ends of the metal core to outside. A first circuit area(11) and a second circuit area(12) are formed on bent both sides of the exposing unit. An insulating layer is formed on both surfaces of the metal core. A circuit pattern is formed on the top of the insulating layer. A part of the circuit pattern and the surface of the insulating layer are covered by a solder resist. A through hole passes through the insulating layer, or the insulating layer and the metal core. |
