PROBLEM TO BE SOLVED: To obtain coated bodies of ferrite granules, capable of providing a high density ferrite electronic part having homogeneous and excellent electromagnetic characteristics, further to obtain a molded product the coated bodies of the ferrite granules obtained by using the ferrite granule coated body, formed by a pressure forming by using a low forming pressure, without impairing the life of the mold, and capable of providing a ferrite electronic part which has the before properties, and further to provide the high density ferrite electronic part excellent in electromagnetic characteristics by using the molded product. SOLUTION: This material for producing a high density ferrite electronic part comprises coated bodies of ferrite granules having at least a part of the surfaces coated with a hexitan ester of a higher fatty acid. The amount of the hexitan ester of the higher fatty acid is in the range of 0.1-3.0 wt.% based on the weight of the ferrite granule. The production method of the high density ferrite electronic part comprises granulating the ferrite powder, adding the hexitan ester of the higher fatty acid to the obtained granules, bringing both into contact with each other thoroughly to coats at least a part of the surfaces of the ferrite granule with the hexitan ester of the higher fatty acid. The formed body for producing the high density ferrite electronic part consists of the formed product of the coated bodies of the ferrite granuless having at least a part of the surfaces coated with the texitan ester of the higher fattey acid. |
