An abnormality sign diagnosis apparatus uses measurement data on equipment to find a difference between previously acquired data in normal operation and measurement data at a time targeted for diagnosis so as to detect abnormality of the equipment. The apparatus includes: input means that inputs the measurement data on the equipment in operation and a surrounding environment and status of the equipment in operation; storage that stores the data on the equipment in normal operation; and processing means that selects data on the equipment in normal operation in a surrounding environment and status of the equipment similar to the surrounding environment and at a time which is targeted for diagnosis, the processing means further detecting abnormality of the equipment using the data of the equipment in normal operation at the time targeted for diagnosis and the data on the equipment in normal operation selected from the storage.
