Abstract: A aerospace machine element product (1) to be managed comprises a plurality of assembled components (2) ((1) to (3)). Each of the plurality of components (2) ((1) to (3)) is manufactured through a material purchase process (S1), a forging process (S2), a heat treatment process (S3), a grinding process (S4), surface treatment process (S5), and inspection process (S6). The information of the processes (S1) to (S2) is recorded on an IC tag (4) together with the lot numbers of the processes. After the components (2) have been assembled in the aerospace machine element product (1), the recorded information regarding the components (2) on the IC tag (4) is recorded in a management computer system (11) so as to be related to a manufacturing number or a manufacturing lot number. Another IC tag (10) is attached to the aerospace machine element product (1) and the manufacturing number or the lot number is recorded on the IC tag (10).
