In a sensor sheet, first electrodes ( 11 ) each covered with a pressure-sensitive resistive member and second electrodes ( 21 ) each covered with a pressure-sensitive resistive member are disposed to extend perpendicularly to each other in a plan view. A core member ( 40 ) made of a hard material is disposed over four detection regions where the first electrodes ( 11 ) and the second electrodes ( 21 ) overlap each other in a plan view. X-, Y-, and Z-axial components (Fx, Fy, Fz) of a force (F) externally applied to the sensor sheet ( 1 ) are detected on the basis of changes in the contact resistance values (R 1 , R 2 , R 3 , R 4 ) corresponding the four detection regions over which one core member ( 40 ) is disposed.
