The component mounting line includes: a time limit management unit configured to manage an elapsed time period of a member; and a usability determiner that determines whether the member is usable based on the elapsed time period of the member. The elapsed time period is a time period that has elapsed after the member is exposed to the air, and the member comprises at least one of a substrate, solder, and a component other than the solder.
