The invention relates to a metal printed circuit board having an aperture reflection plane and the manufacturing method thereof, wherein a technology for forming the reflection plane through the surface processing of a metal circular plate and a jointing technolgy for forming a perforated printed circuit board (PCB) are carried out through a single technology, thereby improving the simplificaiton of the manufaturing technology and the usability of products. The metal printed circuit board includes the metal circular plate which is provided with a primary refleciton plane formed at a chip jointing area through the surface processing; a PCB layer which is laminated on the metal circular plate and is provided with an aperture and a wiring pattern formed on the chip jointing area; a secondary reflection plane formed on the inner side surface of the holes of the PCB layer, and a dam which is formed on the PCB board surrounding the hole by taking the hole as the center.
