Abstract: The present invention relates to a coil element and a manufacturing method thereof. The coil element includes a ceramic body and an internal electrode coil pattern which is formed in the ceramic body. The ceramic body includes NiZnMn ferrite. The internal electrode coil pattern is made of Cu. The NiZnMn ferrite according to the present invention widens a sintering process window by increasing the resistivity of a material through suppressing conductivity due to the generation of an extract in an NiZn ferrite material under a thin oxygen atmosphere by adding Mn to an existing NiZn ferrite composition, and implements the feature of the material by one sintering process.
