A transformer for use in a power supply has a primary winding, a secondary winding, a bobbin on which the primary and secondary windings are separately wound, and a core subassembly mounted in the bobbin. An opening is formed in the cylindrical portion of the bobbin, and an inside core in the magnetic core insertion hole and an outside core located outside the hole are adhesively bonded together via a spacer through the opening in the cylindrical portion.
