There is a need to improve estimation accuracy of a failure estimation method or its failure estimation apparatus that performs failure estimation on a targeted instrument based on history information about several instruments mounted with the same type of semiconductor device as an instrument targeted at failure estimation. A failure estimation apparatus that includes a history information database storing history information about a plurality of instruments mounted with the same type of semiconductor device and performs failure estimation on a targeted instrument mounted with a semiconductor device whose type equals the type, wherein the history information contains operation information and failure information; wherein the operation information indicates a chronological operating state of the semiconductor device mounted on the instruments; wherein the failure information indicates a failure cause of a failed instrument; and wherein the operating state is categorized into a plurality of classifications.
