摘要： An inductance component and a preparation method thereof, comprising: prefabricating a continuous coil row containing a plurality of hollow coils with the connections of every two adjacent hollow coils being bent feet; placing the continuous coil row into a cavity of a prefabricated mold, the cavity comprising a plurality of sub-chambers and one sub-chamber being used for placing a hollow coil; injecting the prepared soft-magnetic magnetic glue into the cavity to enable the soft-magnetic magnetic glue to coat the hollow coil, and simultaneously exposing the bent feet to the outside to perform magnet forming; cutting the formed semi-finished product; and peeling the exposed bent foot copper wire, and performing metallization to form an electrode to obtain a finished product of the inductance component. The invention has high inductance preparation efficiency, and the obtained product electrode has no risks of a dry joint, poor contact, and the like.
