A voltage/current transformer for metering is provided to improve durability by reducing a charge amount of a partial discharge which is generated in the voltage/current transformer. A voltage/current transformer(1) includes power I/O terminals(10,11), a current transformer(20), and a voltage transformer(30). The current transformer is arranged at one side of a main body and includes a primary coil, a secondary coil, and an iron core. The current transformer converts a high current from the power I/O terminals to a low current. The voltage transformer is arranged at the other side of the main body and includes a primary coil, a secondary coil, and an iron core. The voltage transformer converts a high voltage to a low voltage. At least one of the primary coil of the current transformer and the secondary coil of the current transformer is enclosed with a carbon tape(60).
