A communications processing section of a management apparatus sends a request for malfunction information via the Internet to one or more electrical devices being managed. A database manager of the management apparatus refers to data stored in a database and updates the record of the electrical device therein. A timing control section of the management apparatus carries out control so that the number of electrical devices requested upon by the management apparatus does not exceed a predetermined value. In this way, despite the management apparatus centrally manages the malfunction information of each electrical device, a peak quantity of the malfunction information received by the management apparatus can be suppressed and the workload on the management apparatus can be relieved, as opposed to the case where each electrical device sends the malfunction information at its own timing. As a result, a management system of electrical devices is provided, which is capable of managing malfunction information of electrical devices without putting a heavy workload on the management apparatus.
