PROBLEM TO BE SOLVED: To provide a bent amount measuring device having a simple structure.SOLUTION: A bent amount measuring device 1 uses first and second sheet-like elastic bodies 21, 22 having the same material as dielectrics, and includes a sensor part 2 obtained by forming a first capacitor C1 and a second capacitor C2 with first to third sheet-like conductive elastic bodies 23 to 25 that nip these dielectrics in a sandwich state as electrodes. When the sensor part 2 is bent-deformed to the side of the first sheet-like conductive elastic body 23, a value of an alternative current flowing to the second capacitor C3 becomes high, the alternative current flows to the terminal of the second sheet-like conductive elastic body 24, and a bent amount measuring voltage Vo is outputted from an electric circuit part 3. |
