Abstract: Disclosed is a low-cost deformation sensor which is light-weighted and flexible. The deformation sensor stably operates with high responsivity in the air. Specifically disclosed is a deformation sensor (6) which is a sheet composed of a nonaqueous polymer solid electrolyte (10) and at least a pair of electrodes (7, 8) sandwiching the nonaqueous polymer solid electrolyte (10). The nonaqueous polymer solid electrolyte (10) contains a polymer component which is selected from at least either of a polymer containing a monomer unit having a heteroatom and a block copolymer containing a block of the polymer, and an ionic liquid. The sensor generates an electromotive force when deformed, and is able to sense the position of deformation and the pressure distribution.
