Surface-mounted magnetic bead and manufacturing method thereof

The invention particularly provides a patch type magnetic bead and a manufacturing method thereof. The patch type magnetic bead comprises a first magnetic core, a second magnetic core and an end pole piece, the first end of the first magnetic core is provided with a groove; the first end of the second magnetic core is connected with the first end of the first magnetic core, and an air gap is formed between the second magnetic core and the groove; the end pole piece penetrates through the groove and is connected with the first magnetic core at the groove; and two ends of the end pole piece are respectively connected with the second end of the second magnetic core. The manufacturing method of the patch type magnetic bead 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 rectangular-ambulatory-plane shape through a metal sheet and then cut in half, and the end of t
