PROBLEM TO BE SOLVED: To fulfill a sensor function for measuring a change with elapse of time of a pressure distribution on a two-dimensional plane, and both characteristics of executability and workability like adaptability to a curved surface when using a pressure-sensitive sensor structure, smoothness of the surface, or integration of the sensor structure, by a pressure-sensitive sensor or a pressure-sensitive sheet. SOLUTION: Conductive threads having conductivity are arranged on both surfaces of an upper surface part and an under surface part of a multilayered structure fiber structure having a compression characteristic and a compression recovery characteristic. When the multilayered structure sheet is pressed, a bonding part for keeping the upper surface part and the lower surface part of the multilayered structure at a fixed interval is compressed, to thereby bring each conductive thread arranged on the upper surface part and the lower surface part into contact with each other. At that time, since an electric resistance between each conductive thread on both surfaces is changed, a pressure onto the multilayered structure sheet surface can be detected by detecting the change of the electric resistance. When the multilayered structure fiber structure constituting this pressure-sensitive sensor sheet is manufactured, the conductive thread is woven, knitted or sewn simultaneously.
