Method for fabricating touch substrate, touch substrate, substrate and touch device

A substrate for forming a touch substrate, comprising:

• a first electrode layer comprising a metal strip at an edge region of the first electrode layer and a first metal mesh pattern connected with the metal strip, and
• a second electrode layer at one side of the first electrode layer, the second electrode layer comprising a metal strip at an edge region of the second electrode layer and a second metal mesh pattern connected with the metal strip of the second electrode layer, the second metal mesh pattern being insulated from the first metal mesh pattern, and the metal strip of the first electrode layer being in direct contact with the metal strip of the second electrode layer to form a metal stack,
• wherein the metal stack is used for forming a wire electrically connected with one of the first metal mesh pattern of the first electrode layer and the second metal mesh pattern of the second electrode layer.
