Inductor and manufacturing method thereof

The invention particularly provides an inductor and a manufacturing method thereof. The inductor comprises a first magnetic core, a second magnetic core and an n-shaped end pole piece. The first end of the first magnetic core is provided with a first groove and a second groove which are parallel to each other; the first end of the second magnetic core is connected with the first end of the first magnetic core, and a first air gap and a second air gap are formed between the second magnetic core and the first magnetic core; the middle part of the end pole piece is arranged in the first groove and the second groove; and three end parts of the end pole piece respectively extend to the outer side of the second end of the first magnetic core. The manufacturing method of the inductor comprises the steps that the first magnetic core, the second magnetic core and the end pole piece are sequentially machined and then fixed through mucilage glue, the end pole piece is machined into a shape like a Chinese character'ji 't
