A radiator structure includes a base and conductive components. Several fins extend from the base and the conductive components are arranged in the base and the fins in a way of being distributed in orderly pieces in the base and the fins. The base and the fins are made of a metallic material with better heat dissipation rate and the conductive components are made of a metallic material with better heat conductivity so that integral heat dissipation efficiency of the radiator is enhanced largely.
