PROBLEM TO BE SOLVED: To provide a capacitive type sensor sheet that has a high expansion rate, is excellent in reliability when repeatedly used and can be optimally used for measuring an amount of deformation distortion.SOLUTION: A capacitive type sensor sheet according to the present invention comprises: a dielectric layer that is composed of an elastomer composition; a front side electrode layer that is stacked on a surface of the dielectric layer; and a rear side electrode layer that is stacked on a rear surface of the dielectric layer. The front side electrode layer and the rear side electrode layer at least partially face each other across the dielectric layer, and the capacitive type sensor sheet is configured to define a portion where the front side electrode layer and the rear side electrode layer face each other across the dielectric layer as a detection unit. The front side electrode layer and the rear side electrode layer are composed of a conductive composition containing carbon nano-tubes, and the elastomer composition contains urethane rubber with polyetherpolyol as a polyol component, and HDI-based polyisocyanate as an isocyanate component. |
