Abstract

PROBLEM TO BE SOLVED: To provide a liquid-leak detecting body by which the leak of a liquid can be detected immediately. SOLUTION: In this liquid-leak detecting body, a sheet material 9 which is arranged in the lower part of a transfer tube 2 is provided, and a thin foillike conductive passage 10 which is arranged on the sheet material 9 is provided. The sheet material 9 is formed of a polyethylene resin which has an electric insulating property and which can be melted when a high-temperature liquid 1 such as a molten salt or the like is brought into contact. The conductive passage 10 is formed by transferring or vapor-depositing a metal. When the high-temperature liquid 1 which is leaked in the coupling part or the like of the transfer tube 2 is dropped onto the sheet material 9, the sheet material 9 is fused, the conductive passage 10 is broken down, and the electrification of a current for detection is cut off.
