A transformer includes a primary side module, a secondary winding structure, and a magnetic core assembly. The primary side module includes a primary winding structure, a first covering structure and a second covering structure. The primary winding structure has a first opening. The first covering structure includes a second opening corresponding to the first opening and a first receiving recess for accommodating the primary winding structure. The first receiving recess is covered and sealed by the second covering structure. The second covering structure includes a third opening corresponding to the first opening. The first opening, the second opening and the third opening are in communication with each other to be defined as a channel. The secondary winding structure includes a fourth opening, which is in communication with the channel. The magnetic core assembly is partially embedded within the channel and the fourth opening.

A combined structure of hollow bobbin and conductive sheet for a transformer includes a hollow bobbin and at least one conductive sheet. The hollow bobbin includes an outer surface and at least one positioning structure formed on the outer surface. The conductive sheet is fit on the outer surface of the hollow bobbin and includes a main body and at least one engaging structure. The main body has a hollow portion, making the main body to have an inner circumference. The engaging structure is formed on the inner circumference of the main body and is engaged with the positioning structure of the hollow bobbin. The transformer includes at least one winding disposed on the outer surface of the hollow bobbin and abutting against the conductive sheet.
