Characters of the disclosed superfine magnetic element are that possessing laminated structure formed by alternated composite lamination layer and ferromagnetic particle layer; the composite lamination composed of metal particles and ferromagnetic particles. The invention possesses high maximum magnetic energy product and reduced size of magnetic element markedly. The electrochemical manufacturingmethod includes following steps:(1)submerging mask plate to electrolyte of containing ferromagnetic particles; (2)connecting negative pole of power supply of electroform to mask plate, and connectingpositive pole of the power supply to anode; (3)using mask in the mask plate to restrict deposition area;(4) placing a block of magnet behind the mask plate;(5)turning loop of electroform on/off regularly to form deposition layer in lamination structure on the mask plate.
