The present invention is to prevent permeation of moisture and to improve earthing force by combining a copper wire of a ground wire and a ground wire connection terminal to a connection terminal combining hole completely and closely. When the ground wire connection terminal for an earth bar of the present invention is configured, the ground wire connection terminal is tapered to be able to be easily combined to the connection terminal combining hole which is formed at an upper part of the earth bar. Especially, one or two copper wire combining parts to combine the copper wire of the ground wire in a length direction to one side of the ground wire connection terminal are configured, or the copper wire combining part to combine the copper wire of the ground wire is formed. According to the present invention, since the copper wire of the ground wire and the ground wire connection terminal can be combined by backstitch deeply in the length direction into the connection terminal combining hole of the earth bar, the ground wire connection terminal and the copper wire and the connection terminal combining hole of the earth bar can be combined completely and closely. Also, the ground wire connection terminal of the present invention has the advantage of being able to prevent permeation of moisture into the connection terminal combining hole of the earth bar and to form an earthing area widely.
