A ground terminal (11) has a fixing portion (12) formed with a bolt hole (12a) for receiving a bolt (B) for fixing the fixing portion (12) to a mount member (A), a wire-connecting portion (13) for fixing a wire, and a coupling portion (14) between the fixing portion (12) and the wire-connecting portion (13). The coupling portion (14) is formed with a pointed fracture groove (15) extending in widthwise direction and having an apex (15a) symmetrically disposed the coupling portion (14). The ground terminal (11) can be easily fractured and separated with the apex (15a) of the fracture groove (15) as a fracture starting point by lifting the wire connecting portion (13) up to bend the ground terminal (11).
