ABSTRACT:
A tablet that hardly causes the fluctuation in the sheet resistance on a film substrate despite the small size of the tablet. The edge of one side of the film substrate requiring a notch for connector insertion are provided with other notches having the same depth as that of the notch for connector insertion, thereby notching most of the edge to the same depth.
