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 ( 4 a to 4 c) each holding a chemical, and a chemical ID to identify the chemical held in each of the containers ( 4 a to 4 c) 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 ( 4 a to 4 c) 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).
