Pressure-sensitive sensor

A pressure-sensitive sensor comprising:

• a conductive cloth having a mixture of conductive carbon black and a binder resin applied thereto;
• a first-electrode cloth disposed on a first-surface of the conductive cloth;
• and a second-electrode cloth disposed on a second-surface of the conductive cloth,
• wherein the conductive cloth is a knitted fabric composed of non-conducting fiber yarns, the first-conductive cloth is a knitted fabric in which a plurality of first-electrodes composed of conducting fiber yarns are formed at first-intervals, the second-conductive cloth is a knitted fabric in which a plurality of second-electrodes composed of conducting fiber yarns are formed at second-intervals, and the first-electrodes and the second-electrodes are arranged in a direction intersecting with each other, or wherein the conductive cloth is a knitted fabric composed of non-conducting fiber yarns, the first-electrode cloths and the second-electrode cloths are knitted fabrics composed of conducting fiber yarns, the first-electrode cloths and the second-electrode cloths are arranged in directions intersecting with each other, and areas of intersection between the first electrode cloths and second electrode cloths are formed so as to have a matrix structure, and
• wherein courses or wales of the first-electrode cloth are arranged so as to be parallel or orthogonal to courses or wales of the conductive cloth, and courses or wales of the second-electrode cloth are arranged so as to be parallel or orthogonal to the courses or wales of the conductive cloth.
