PROBLEM TO BE SOLVED: To provide an eyelid pressure sensor capable of sufficiently transmitting eyelid pressure to a pressure sensor and capable of stably and accurately detecting the eyelid pressure.SOLUTION: A pressure sensor 27 for detecting pressure is provided at a tip of a flexible detection board 23 formed in a long shape. A backing plate 28 is provided in such a manner as to cover the pressure sensor 27. A peripheral edge of the backing plate 28 is formed in such a shape as to have a convexly-curved cross-section, and a surface of the backing plate 28 is formed like a spherical surface. |
