Abstract: A sensor sheet is manufactured by forming a conductive heat-sensitive material 5 over first wiring electrodes 3a and forming second wiring electrodes 4a over the conductive heat-sensitive material 5. For this reason, no adhesion surface (boundary surface), which is formed when adhesion is performed later, exists between the first wiring electrode 3a and the conductive heat-sensitive material 5 and between the conductive heat-sensitive material 5 and the second wiring electrodes 4a.

Abstract: The body pressure distribution sensor sheet includes a first sheet, a second sheet, and a plurality of pressure-sensitive regions interposing between the first sheet and the second sheet. The pressure-sensitive regions are arranged in two directions, i.e., a lengthwise direction and a transverse direction to form a matrix. A first opening, a second opening, and a cut line are formed in an area between a pair of pressure-sensitive regions and adjacent to each other in a first oblique direction. The shape of the first opening is defined by a plurality of borders including a border and a border. The border extends from one end of the cut line in the transverse direction, and the border extends from the one end of the cut line in the lengthwise direction. The shape of the second opening is defined by a plurality of borders including a border and a border.
