An operation for a chemical of indefinite form is managed so that operation record of the chemical is traceable. An IC tag (3) is attached to various containers (4a to 4c) each holding a chemical, and a chemical ID to identify the chemical held in each of the containers (4a to 4c) is stored in the IC tag (3). When an operation involving a mass change or a change of composition information is carried out, such as apportioning, mixing, reacting, and separating, while the containers (4a to 4c) serve as receivers of the chemical, a record management apparatus (1) newly generates a chemical ID, and a IC tag terminal (2) updates the chemical ID in the IC tag (3) to the new chemical ID. In addition, the record management apparatus (1) manages a correspondence between the chemical ID stored in the IC tag (3) (old chemical ID) and the chemical ID newly stored in the IC tag (3) (new chemical ID).
