A transformer includes a primary coil unit including a primary winding, a first insulating portion and a shielding layer, wherein the first insulating portion wraps the primary winding, the shielding layer covers an outer surface of the first insulating portion, the shielding layer includes an opening, and a part of the first insulating portion is exposed at the opening; an outgoing wire terminal in the opening and having a first portion and a second portion connected with each other, the first portion coupled to the primary winding and wrapped by the first insulating portion, the second portion being exposed out of the first insulating portion; a connecting wire having a first end connected to the second portion of the outgoing wire terminal; and an insulating sleeve partially wrapping the connecting wire, and a second end of the connecting wire being exposed out of the insulating sleeve, (FIG. 17).

A laminated coil and manufacturing method therefor are disclosed. The laminated coil comprises multiple lamination units formed after a base body is folded. The lamination unit comprises an opening, a first common edge, and a second common edge; opening directions of two adjacent lamination units are opposite; the lamination unit is separately jointed with two adjacent lamination units by means of the first common edge and the second common edge, so that the base body in a laminated state forms a spiral power-on path. The base body is sequentially folded to form multiple lamination units, so that the base body in the laminated state forms the spiral power-on path to improve energy efficiency of a rectangular coil. In addition, on the basis of the laminated coil structure, the manufacturing method provided is adopted, and high precision of laminated coil can be highly efficiently manufactured.
