description PROBLEM TO BE SOLVED: To provide a fine particle measuring device which accurately measures the leakage or amount of fine particles contained in exhaust gas with a simple structure.SOLUTION: A fine particle measuring device includes; a fine particle sensor which has different kinds of metal layers on a surface of an insulative substrate and whose forefront side is exposed to exhaust gas; potential difference detection means for detecting a potential difference which occurs between the different kinds of metal layers on a rear end side of the fine particle sensor based on a temperature difference between the forefront and rear end sides of the fine particle sensor; and measurement means for measuring the leakage or amount of fine particles contained in the exhaust gas based on the detection result by the potential difference detection means.
