A transformer includes a first winding member, a second winding member, a primary winding coil, a secondary winding coil and a magnetic core assembly. The first winding member has a first channel penetrating therethrough. The second winding member has a second channel penetrating therethrough and includes a covering part. The covering part has a receptacle communicating with the second channel. The primary winding coil is wound on the first winding member. The secondary winding coil is wound on the second winding member. The magnetic core assembly is partially embedded into the first and the second channels. The combination of the first winding member and the primary winding coil wound on the first winding member is accommodated within the receptacle, such that the primary winding coil and the secondary winding coil are separated from each other by the covering part and the first channel communicates with the second channel.
