The efficiency of the work of ground connection to a vehicle body panel is enhanced and the number of parts is decreased. A ground connector (10) integrally molded with a conductive resin comprises a pair of facing pieces (13) one ends of which are interconnected via a connecting section (14), a pair of holding pieces (15) formed by folding back the other ends defining an opening (16) into the space defined by the facing pieces (13), a displacement section (17) projecting from the internal surfaces of the facing pieces (13), disposed between the holding pieces (15) and the connecting section (14), connected between the internal surfaces of the facing pieces (13), and forming a V shape projecting toward the opening (16), and a piercing piece (18) projecting from a center projecting portion(17c) of the displacement section (17) toward the connecting section (14). A ground wire (32) is inserted into a ground-wire insertion space (19) defined between the piercing piece (18) and the connecting section (14), the ground connector is attached to an end edge (36a) of a vehicle body panel (36) through the opening (16), the holding pieces (15) are brought into contact with the top and bottom surfaces of the vehicle body panel (36), the insertion force of the vehicle body panel (36) causes the vehicle body panel (36) to push the displacement section (17) toward the connecting section (14) thus to reverse the projection of the displacement section (17) toward the connecting section (14), and the piercing piece (18) pierces the insulation cover (32a) of the ground wire (32) to come into contact with the conductor (32b) of the ground wire (32).
