(Prior Art) Conventionally, an automobile mat is commercially available in which a pile made of insulating fibers is driven into a predetermined volume on a base fabric using insulating fibers.

However, since this automobile mat is made of an insulating material, static electricity is easily generated due to friction with the hem of shoes or pants when the automobile is getting on or off or while driving. As a result, the automobile mat is charged with electricity, dust and dirt are easily attached to the mat, and the mat is easily soiled and must be cleaned frequently. In addition, the static electricity generated by friction will charge not only the car mat but also the human body, and when you touch the metal part of the car when getting on or off, the static electricity accumulated in the human body will be suddenly transferred to the metal part. It was grounded and gave a large electric shock to the human body.
