A defuzzifying apparatus, for a fuzzy inference machine in which the consequent of a fuzzy inference is represented by a fuzzy set or a singleton, comprises a bias impression unit that adds an arbitrary-largeness bias value to each inference output grade, and circuitry a center of gravity of each inference output grade after the bias value is added. If the fuzzy inference is accomplished by hardware, it is possible to improve fluctuation of a final output due to noise or inference grade error. Even when an input does not match with any rule, any abnormal output can be prevented.
