PURPOSE: A metal PCB, a manufacturing method thereof, and a light emitting device with the same are provided to extend the lifetime of the light emitting device by increasing heat dissipation efficiency through the metal PCB. CONSTITUTION: Two main surfaces and four side surfaces of a metal sheet are oxidized(S3). An insulating resin layer is formed on one side of a copper sheet. A copper insulating sheet is formed(S4). The insulating resin layer of the copper insulating sheet is located on a first main surface of the oxidized metal sheet. The copper insulating sheet is attached on the metal sheet using thermo-compression bonding(S5). A circuit pattern is formed by etching the copper sheet(S6).
