The present invention relates to a capacitive sensor sheet for measuring the amount of deformation of a measuring object with high sensitivity and high accuracy. The capacitive sensor sheet of the present invention includes a sensor body； and a stretchable cloth integrally formed with the sensor body and having anisotropy in terms of stretchability, the sensor body including: a sheet-like dielectric layer including an elastomer composition； and a first electrode layer and a second electrode layer each including an electroconductive composition containing an electroconductive material, wherein the first and the second electrode layers are formed on a top surface and a bottom surface of the dielectric layer respectively, and are at least partially opposed to each other across the dielectric layer, the at least partially opposed portions of the first and the second electrode layers constitute a detection portion, and the sensor body is reversibly deformable to change areas of the top and bottom surfaces of the dielectric layer.
