Transformer and plate coil shaped parts

The transformer includes a magnetic core and a primary module and the upper secondary coil module, and the lower secondary coil module. Magnetic core former having an internal space, takes place in the rear an opening type. The primary module comprising a primary coil formed on a coil support, and the coil support arranged in the magnetic core. Upper secondary coil module provided with a top insulating molding body, and the ends have been embedded in the insulating molded body upper side to the exposed state in which the upper plate-shaped coil disposed to be opposed to the primary coil disposed in abutting to the upper magnetic core of the coil support do. Lower secondary coil module provided with a lower insulating molded body, and the ends are isolated lower in the exposed state is embedded in molding material of the lower plate-shaped coil disposed to face the first coil disposed in the magnetic core abut at the lower side of the coil support do.
