An electronic package includes a bearing structure, a plurality of electronic components disposed on the bearing structure and electrically connected to the bearing structure, a cladding layer formed on the bearing structure, and a sheet-like functional member embedded in the cladding layer and having at least one through hole exposing the functional member through the cladding layer. Therefore, the functional part can dissipate heat only by being close to the periphery of the electronic component without being combined with the electronic component, so that the heat dissipation area on the bearing structure is increased.
