PROBLEM TO BE SOLVED: To suggest a quality control method of mechanical element articles for aerospace by which detailed history information about the respective element articles from purchase of materials to inspection content after completion is easily controlled in one-to-one relation with the mechanical element articles for aerospace. SOLUTION: The mechanical element article 1 for control is manufactured from purchase of the materials S1 via a forging process S2, a heat treatment process S2, a grinding process S4, and a surface treatment process S5. Pieces of information about the respective processes S1-S2 are recorded in an IC tag 4 with lot number of the processes. After assembling an element article 2 to the mechanical element article 1 for aerospace, the pieces of recorded information of the IC tag 4 about the respective element materials 2 are recorded in a control computer system 11 corresponding to manufacturing numbers or manufacturing lot numbers. Another IC tag 10 is attached to the mechanical element article 1 for aerospace and the manufacturing number or the lot number is recorded. In addition, in the IC tag 10, processing condition information about the respective processes of forging, heat treatment, grinding, and surface treatment are recorded.
