An earth bolt with a surface treatment layer are a method of surface treatment of the earth bolt are provided. The surface treatment includes a tin-zinc plated layer, a colored chromate film layer and a silicate coating layer. Since the earth bolt with the surface treatment layer has improved electro-conductivity and anti-rusting property, it may protect electrical/electronic components fitted to a vehicle from electromagnetic shock and remove noise therefrom, thereby improving reliability of a vehicle body.
