Transformer for LDC of electric automobile

The present invention relates to a transformer for an LDC for an electric vehicle, and according to the present invention, an LDC (100) for an electric vehicle (V), which supplies power supplied through a high-voltage battery (30) of the electric vehicle (V) to electric components of the electric vehicle, is characterized by comprising: a flat-plate-type primary coil (110) for receiving current supplied from the high-voltage battery (30) of the electric vehicle; a lower secondary coil element (120) which is formed in close contact with the lower surface of the primary coil (110) from the lower surface of the primary coil (110), generates an induced current by means of the current flowing through the primary coil (110), and supplies the induced current to electrical components of an electric vehicle (V); and an upper secondary coil element (130) which is formed in close contact with the upper surface of the primary coil (110) from the upper surface of the primary coil (110), generates an induced current by mea
