PROBLEM TO BE SOLVED: To provide a sulfur component detector easily calculating an accumulated value of a sulfur component in an exhaust gas. SOLUTION: A metal or a metallic compound 50, capturing the sulfur component in an exhaust gas is disposed in a flow path of an exhaust gas. Physical properties of the metal or the metallic compound 50, changed according to increase or reduction of the sulfur component captured by the metal or the metallic compound 50 are measured for calculating the amount of the sulfur component captured by the metal or the metallic compound 50, based on the measured physical properties. When the captured amount is increased, the captured amount is added up, when the sulfur component is discharged from the metal or the metallic compound 50, the renewal function of the accumulated value of the captured amount is stopped, and the accumulated value of the captured amount is calculated. The accumulated amount of the sulfur component contained in the exhaust gas is calculated based on the accumulated value of the captured amount. COPYRIGHT: (C)2009,JPO&INPIT
