Abstract: Provided are a quality inspection method and a quality inspection system for unvulcanized rubber material. A final dielectric constant measurement device detects the dielectric constant of a final rubber material in which a compounding agent of predetermined type is mixed with unvulcanized rubber, and a calculator calculates a compounding ratio of the compounding agent to the final rubber material based on the detected dielectric constant, determines whether or not the calculated compounding ratio is in a preset compounding reference range, displays a determination result on a monitor, and adjusts a ratio of the compounding agent fed into an extruder to the unvulcanized rubber such that the calculated compounding ratio is within the compounding reference range.
