Abstract:
1. A pressure detection unit comprising: a first substrate and a second substrate which are disposed in opposition to each other and subject to load from the outside; a pair of electrodes provided in distribution in the first substrate and the second substrate, the electrodes being disposed linearly in opposition to each other, electrically conductive pressure-sensitive ink disposed between the pair of electrodes to cover at least one of these electrodes and having electrical characteristics which varies according to the load, and an adhesion member for adhering the first substrate and the second substrate to each other with the pair of electrodes being placed in contact with the pressure-sensitive ink, wherein the pair of electrodes are arranged in the form of frames, and the adhesion member has a frame-like first adhesion part disposed in the inside of the pair of electrodes, and a frame-like second adhesion part disposed in the outside of the pair of electrodes.
