PURPOSE: To attain precisely coordinates of a depressed position, by detecting the resistance from one end of one series resistance layer to one end of the other series resistance layer when it is depressed.

CONSTITUTION: A transparent conductive film where an indium oxide is vapor- deposited onto a polyethylen film 2 on an acrylic substrate 1 is etched, and the series resistance layer consisting of split resistance parts 3-1, 3-2... is laminated. Split resistace parts are provided with electrodes 4-1, 4-2... and 5-1, 5-2... in both ends and are connected in series. A tansparent conductive film where a conductive thin film layer consisting of an indium tin oxide is vapor-deposited to a polyethylen film 7 on a spacer consisting of a polycarbonate is etched symmetrically to the series resistance layer with respect to a plane, and split resistance parts 8-1, 8-2... are formed. Electrodes 9-1, 9-2... and 10-1, 10-2... are formed, and this series resistance layer is laminated symmetrically to said resistance layer with respect to a plane.
