Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a maintenance device, a maintenance system and a maintenance method capable of preventing an operation information from leaking to the outside needlessly. SOLUTION: Even when the transmission of information for maintenance is requested from the management device 201 of a vendor office 200, a person in charge of maintenance in a user plant 100 judges whether or not to permit the transmission for the transmission request, and only in the case that the transmission is permitted, only the permitted information for the maintenance is transmitted from a maintenance terminal 140 through the Internet 300 to the management device 201. Thus, the information for the maintenance is effectively prevented from leaking to the outside needlessly.
