Zusammenfassung: | The present invention aims to provide a capacitive sensor sheet excellent in detection sensitivity and detection accuracy in measuring changes in capacitance, and the capacitive sensor sheet of the present invention comprises: a dielectric layer including an elastomer composition (A); a top electrode layer laminated on the obverse surface of the dielectric layer; and a bottom electrode layer laminated on the reverse surface of the dielectric layer, wherein portions at which the top electrode layer and the bottom electrode layer intersect as viewed in a thickness direction serve as a plurality of detection portions, and the capacitive sensor sheet further includes at least one of the following components: a top covering electrode layer formed over the top electrode layer so as to cover the detection portions with a top flexible layer including an elastomer composition (B1) interposed therebetween; and a bottom covering electrode layer formed over the bottom electrode layer so as to cover the detection portions with a bottom flexible layer including an elastomer composition (B2) interposed therebetween, whereby the capacitive sensor sheet is adapted to be used for measuring changes in capacitance in the detection portions. |
