Disclosed is a door operating device with which misoperations or inoperations do not easily occur during locking and unlocking while allowing door handles to exhibit an excellent metallic luster. Specifically disclosed is a door operating device which comprises a door handle (2) disposed on a vehicle door so as to open and close the door; electrodes (4a, 4b) disposed in the door handle (2); a detecting circuit (6) that outputs operating signals for locking and unlocking in accordance with changes in electrostatic capacitance occurring in the vicinity of the electrodes (4a, 4b) when a part of a human body approaches or is brought into contact with the door handle (2); a unit (52L) that locks and unlocks the door in response to the operating signals; and a transmitting/receiving antenna (10) for transmitting/receiving signals between the antenna and a portable unit corresponding to the vehicle. The door handle (2) includes an insulator base (20), and the surface of the base (20) adjacent to the outside of the vehicle is coated with a metallic layer (22) that is composed of an assembly of insular metallic particles separated from each other and that extends along the surface of the base (20).
