<p>Provided is a curve sensor which can be widely and universally applied even to objects to be measured which are only relatively slightly curved. One embodiment of the present invention is a curve sensor for measuring the curve of a curved object to be measured, which curve sensor is provided with a light supply part for conducting light and a curve status detection part, and the curve sensor is equipped with: a curve measuring part which makes it possible to measure the curve status of an object to be measured using the variation in the amount of light which passes through the curve status detection part and is output; a light transmitting part for transmitting light from the light supply part to the curve measuring part; and a retaining part for retaining the light supply part and the curve measuring part in a specific position on the object to be measured.</p> |
