The present invention relates to a safety device for preventing a hand from being pinched in an elevator door, including: a conductive waveguide sheet for a door that is positioned between a car frame provided in an elevator car and a platform and an elevating frame and that is provided on a surface of the elevator door which is opened and closed in response to driving by a door driving motor controlled by a control means, so as to detect electric currents of a human body; the control means, which determines whether or not the electric current which is detected through the conductive waveguide sheet for the door is a microcurrent of a human body; and a first LED that is disposed on one side of the edge of the conductive waveguide sheet for the door, which is to be turned on through the control by the control means and emit light to the conductive waveguide sheet for the door. According to the present invention, the conductive waveguide sheet is attached to the corner portion of the frame of the elevator door or platform and the like, and the elevator door is forcedly controlled when the current of the human body is detected through hand contact so as to prevent the hand from being hurt by being pinched between the elevator door and the frame, and at the same time, light is emitted to the conductive waveguide sheet so that a user can be made aware of the hand pinching risk in a visual manner, thereby providing a visual cue.
