Provided is a bending sensor, which increases the voltage generated between electrode films when deformed following the movement of an object by having a sensor portion formed by sandwiching a polymer electrolyte membrane between a pair of electrode films, the electrode films including embedded a segment copolymer (Z) having a polymer block (S) formed of a structural unit derived from an aromatic vinyl compound and having an ion-conductive group, and conductive particles, and The amorphous polymer block (T) formed of a structural unit derived from an unsaturated aliphatic hydrocarbon, and the block copolymer (Z) have a layered structure. |
