To this end, the present invention provides a coal analyzer 1 equipped with an image acquisition unit 2 for acquiring a surface image of a coal sample 7, an identification unit 3 for identifying a microstructural component group included in the surface image, and a calculation unit 4 for calculating the percentage of at least one type of microstructural component group. The calculation unit 4 calculates, for example, the total inert volume, which is the percentage of inertinite within the microstructural component groups. The coal analyzer 1 is preferably equipped with a correction unit 5 that corrects the total inert volume.
