The pressure-sensitive sensor

A pair of electrodes 16a · 16b, the substrate film 31 to place the at least one electrode, and the upper film 6 facing the base film 31, the coating allows placement of the pair of electrodes 16a · 16b, was added a pressure sensitive ink layer 30 which electrical characteristics are changed by the pressing force, pressure sensor 40 with the spacer 10, the having adhesiveness interposed between the base film 31 and the upper film 6.
