A printing production line system for an electronic device includes a transport chamber with a robot transport line in which a self-traveling robot transports a base material in a sheet-fed manner in a free state, a plurality of processing chambers for forming an electronic device on the base material by printing on at least one side of the transport chamber, and base material transfer areas that performs loading of the base material to the processing chambers from the self-traveling robot and unloading of the base material to the self-traveling robot from the processing chambers. The transport chamber and the base material transfer area communicate with each other through respective openings, and a one-way air flow in each of the openings is formed by making an adjustment such that air pressure in the transport chamber is higher than air pressure in the base material transfer areas.
