DETECTOR AND METHOD FOR DETECTING LEAKAGE OF WATER

摘要

PROBLEM TO BE SOLVED: To easily detect leakage of water in a detection area by generating strain or bending in an optical fiber in the leakage of water, using a water leakage detecting sensor attached to the optical fiber.

SOLUTION: This detector/method for detecting the leakage of the water is provided with a water barrier face member 42 having a water barrier property such as a water barrier sheet and a water barrier layer, the optical fiber 1 arranged at least one face side of the water barrier face member 42, and the water leakage detecting sensor 2 attached to the optical fiber 1 to generate the strain or bending in the optical fiber 1 when detecting the water. When the sensor 2 detects the water, the strain or bending is generated in the optical fiber 1 to detect the water leakage in the water barrier face member 42.
