Abstract
There is provided such a pressure distribution detection device that noise affect is small even when the detection region is increased and no line break occurs even when the device is used for a long period of time. The pressure distribution device detects distribution of the pressure applied. The device includes a first loop electrode line group (1), a second loop electrode line group (2) arranged on the first loop electrode line group (1), an elastic body (3) arranged on the second loop electrode line group (2), and a conductive material (4) arranged on the elastic body (3). The first loop electrode lines (1) are arranged in parallel to one another inside a first surface. The second loop electrode line (2) are arranged in parallel to one another within a second surface parallel to the first surface and fixed at a predetermined distance from the first surface. The second loop electrode lines (2) orthogonally intersect the first loop electrode line (1). The conductive material (4) is movably arranged via the elastic body (3) on the intersection between the first loop electrode line (1) and the second loop electrode line (2). The first loop electrode lines (1) are driven by a drive …
