PURPOSE: An indicating agent for detecting sulfur compounds and a sulfur compounds absorbing agent using the same are provided to rapidly change the color of the indicating agent by easily reacting the sulfur compounds. CONSTITUTION: An indicating agent for detecting sulfur compounds is obtained by carrying a molybdenum compound on the surface of a silica, alumina, or zeolite carrier. A transition metal aqueous solution is prepared by dissolving the transition metal precursor of molybdenum. A support is prepared by carrying the transition metal aqueous solution in a silica, alumina, or zeolite carrier. Moisture is eliminated from the carrier.
