PROBLEM TO BE SOLVED: To obtain a measuring apparatus by which the dispersion degree of a specific mixing agent in a rubber mixture can be displayed quantitatively without relying on a manual operation. SOLUTION: This measuring apparatus, for a dispersion degree, which measures the dispersion degree of a specific mixing agent in a rubber mixture is provided with an imaging means 2 which images the face, to be measured, of a test piece TP composed of the rubber mixture. The measuring apparatus is provided with a first computing means 10 wherein image information imaged by the imaging means 2 is divided into a plurality of region so as to be in a lattice shape, a ratio occupied by the specific mixing agent is detected with reference to the respective regions and the number of regions in which the ratio occupied by the mixing agent exceeds a reference value is found. The measuring apparatus is provided with a second computing means 20 wherein the dispersion degree of the specific mixing agent is computed on the basis of a physical quantity which is decided by the number of regions found by the first computing means 10 and which is decided by the mass and the specific gravity of the rubber mixture and the specific mixing agent. The measuring apparatus is provided with a display means 10 which displays the computed dispersion degree.
