A conductive plate (30) for grounding a plurality of first ground wires (W) to a body of a vehicle includes a conductive plate main body (31) with a body-side grounding portion (34) to be grounded to the body by being bolted to the body. Terminal connecting portions (32B) are on one end of the conductive plate main body (31) and are to be connected to wire-side terminals (21) electrically connected to the respective first ground wires (W). A first rib group (37) and a second rib group (38) project from the conductive plate main body (31) in a thickness direction of the conductive plate main body (31) and set the rigidity of the conductive plate main body (31) to be low at a position close to the body-side grounding portion (34) and high at a position distant from the body-side grounding portion (34).
