Provided is a gas leak locating material used for locating a gas leaking position by application thereof at a position suspected to have a gas leak. The gas leak locating material satisfies the following formula: A/B≥21.0, where A represents a viscosity (Pa·s) of the gas leak locating material at 25° C. at a shear rate of 0.1 sand B represents a viscosity (Pa·s) of the gas leak locating material at 25° C. at a shear rate of 10 s. The gas leak locating material has an elastic modulus E' of 10 MPa or higher at 50° C. after being cured.
