Integrally-formed single all-in-one inductor and manufacturing method thereof

The invention discloses an integrally-formed single all-in-one inductor and a manufacturing method thereof, the inductor comprises a base body, more than two coils and electrodes, the more than two coils are fixedly arranged in the base body respectively, and the electrodes serve as welding pins to be connected to the two ends of the coils respectively. The manufacturing method comprises the steps that S1, two or more copper sheet or copper wire windings are adopted as coils, and the ends of the copper sheets or the copper wires are subjected to surface metallization treatment to serve as inductance electrodes; s2, a copper sheet or a coil in a certain shape is implanted into a magnetic core formed by the soft magnetic composite material and fixed; s3, after the assembly is implanted into a forming mold, soft magnetic composite material powder is added for compression molding; and S4, performing heat treatment and terminal electrode treatment on a compression molding product to form a single multi-inductor co
