A proximity sensor installed inside a vehicle can include: an outer frame formed of a first non-conductive substance and including a first metal layer; an inner frame formed of a second non-conductive substance, including a second metal layer, and disposed in an interior of the outer frame; a sensor electrode contacting the second metal layer; and a sensor Integrated Circuit (IC) connected to the sensor electrode and configured to detect an approach or a contact of a user's hand. The first metal layer can be connected to the ground (GND) so as to confine a sensing field of the sensor electrode to the interior of the outer frame.
