Metallic laminate and manufacturing method of light emitting diode package using the same

A metallic laminate, comprising:

• a core layer made of an insulating material and including a heat radiating filler;
• a metal layer disposed on a first surface of the core layer;
• a heat radiating metal layer disposed on a second surface of the core layer;
• and
• a protective metal oxide layer disposed over the entirety of outer exposed surfaces of the heat radiating metal layer and made of an oxide of the heat radiating metal layer, such that corrosion of the heat radiating metal layer is prevented, wherein:
• wherein the entirety of outer exposed surfaces of the heat radiating metal layer includes a side surface of the heat radiating metal layer.
