A current transformer and a method for manufacturing the same are provided to simplify a work and reduce a labor cost by coupling elastic epoxy resin inside hard epoxy resin with only one mold. A current transformer includes a coil(10), a conductive case(40), elastic epoxy resin(20), and hard epoxy resin(30). The conductive case with predetermined size and width surrounds the coil and includes an insertion hole(41). The elastic epoxy resin is injected through the insertion hole of the conductive case, wraps the coil, and fills the conductive case. The hard epoxy resin wraps an outside of the conductive case.
