A lead-frameless power inductor and its fabrication method are disclosed. The power inductor comprises a lower substrate, a coil provided on the lower substrate, and an intermediate layer which encloses the coil, wherein the lower substrate can be a soft magnetic entrainer or a non-magnetic entrainer. The coil is made of an insulated wire, and the intermediate layer is a colloid consisting of magnetic powder. The steps of fabrication are: forming a wire package to fix on the upper surface of the lower substrate, wherein the wire package is formed of a lacquer insulated copper wire or the like, then coated with a colloid consisting of the magnetic powder, and then is cutting into granulated elements and forming in order. |
