The present invention relates to an operation device which can be easily installed on a vehicle door, and a vehicle door comprising the operation device. An operation device of the present invention comprises: a gripper provided on an inner surface of a door of a vehicle; an operation interface provided on an inner side surface of the gripper for receiving an operation input entered by an occupant to operate at least one in-vehicle device; a first sensor provided on an outer side surface of the gripper for detecting a finger of the occupant; a second sensor provided on at least one of the inner side surface and an upper surface of the gripper for detecting a finger of the occupant; and a controller connected to the operation interface, the first sensor, the second sensor, and the at least one in-vehicle device. The controller controls the at least one in-vehicle device based on a signal from the operation interface when both the first sensor and the second sensor detect the occupant, and prohibits the at least one in-vehicle device from being controlled based on a signal from the operation interface when at least one of the first sensor and the second sensor does not detect the occupant.
