description The invention discloses a planar inductor which comprises a magnetic core. A winding is composed of a top lug plate, a coil and a bottom lug plate which are sequentially arranged, and the top lug plate and the bottom lug plate take the shape of an L. The coil adopts a multiple-layer structure formed by stacking each layer of connecting plate taking the shape like the Chinese character 'ao', and one opening is formed in each connecting plate. The opening directions of the adjacent connecting plates are vertically arranged. Insulation sheets are arranged between the bottom lug plate and the coil, between the top lug plate and the coil and between layers of the coil, and the coil is arranged in the planar magnetic core. The invention also discloses a manufacturing method of the planar inductor. After the insulation sheets are added between the layers of the coil, the coil is put in an embedding mould to be embedded. The coil is folded through a folding tool, the coil and insulation pads are assembled through a p
