PROBLEM TO BE SOLVED: To save the labor of preparing a precise circuit diagram. SOLUTION: For a circuit diagram set in an existing circuit diagram file A comprising one or more circuit diagram sheets, it is determined whether or not a device having a plurality of terminals including a power supply terminal and a grounding terminal, a symbol diagram showing the power source terminal and the grounding terminal of which is not present in the circuit diagram, is present. When such a device is present, a circuit diagram sheet is added as required (B), and a power supply circuit diagram 36 in which a symbol diagram showing only the power supply terminal of the device is arranged, and the power source terminal is connected to a feeding terminal, and a grounding circuit diagram 38 in which a symbol diagram showing only the grounding terminal of the device is arranged, and the power supply terminal is connected to an earth are further automatically added.
