The invention discloses an anti-static device as well as a production method and a substrate thereof. The anti-static device comprises a first conducting layer, a first insulating layer, an active layer, an etch-resisting layer, and a second conducting layer, wherein the first insulating layer is formed on the first conducting layer; the active layer is formed on the first insulating layer; the etch-resisting layer is formed on the active layer; the second conducting layer is formed on the etch-resisting layer, and comprises a first part and a second part which are spaced from each other; the first part and the second part of the second conducting layer are electrically connected with the active layer via a first through hole and a second through hole formed in the etch-resisting layer respectively; either the first part or the second part of the second conducting layer is electrically connected with the first conducting layer via a fifth through hole which penetrates the etch-resisting layer and the first insulating layer. As the second conducting layer is electrically connected with the first conducting layer via the independent through hole, the potential difference between the first conducting layer and the second conducting layer can be eliminated promptly, and the phenomenon of electrostatic breakdown in a production process can be avoided effectively.
