An opening-and-closing device for vehicle door includes: a close-latch mechanism; an electric-powered releasing mechanism; an association mechanism; a relay mechanism; an electric open/close unit; and a control unit. The relay mechanism switches from a connection state to a disconnection state by the operation of an association mechanism in a cancellation direction to allow returning a first ratchet stopped at a release position. The control unit reversely controls the electric open/close unit, operates a door to be opened toward a fully opened position, operate the association mechanism in a cancellation direction, and switches the relay mechanism to the disconnection state, upon detection of operational malfunction of the electric-powered releasing mechanism during closing of the door from the fully opened position to a fully closed position by closing operation of the electric open/close unit.
