Conductive winding structure and transformer device using the same

A conductive winding structure is applied to a magnetic component and at least comprises a plurality of conductive units and at least a connection part. Each conductive unit is provided with a main body, a first end part and a second end part; the main body is connected with the first end part and the second end part, and is provided with a hollow hole; the connection part is provided with a first side end and a second side end, and used for connecting any two adjacent conductive units; the first side end of the connection part and the first end part of one of the plurality of conductive units form a first connection position; the second side end of the connection part and the second end part of the adjacent conductive units form a second connection position; the conductive units, the connection part, the first connection position and the second connection position are folded to enable the conductive units to be arranged oppositely; and a plurality of hollow holes of the conductive units correspondingly form
