PROBLEM TO BE SOLVED: To provide a stain measuring instrument capable of quantitatively showing the adhesion amount of a stain, easy to grasp the adhesion state of the stain and capable of measuring even a slight stain, and to provide a stain measuring method. SOLUTION: A pair of V blocks 12a and 12b are fixed on both ends of the upper surface of a sample stand 11 and a heating pipe 1 can be placed as a test member. The sample stand 11 can be moved to the left and right by driving a motor 10a, and an infrared semiconductor laser 17a and an infrared sensor 17b are attached to the back of the leading end of an arm 14, in a state of facing each other so as to hold the heating pipe 1.
