PROBLEM TO BE SOLVED: To provide a power supply circuit which can rapidly perform electrical opening of a power supply line applying a supply voltage to a load if an excess current flows to the power supply line, and can be actualized more inexpensively than before. SOLUTION: The power supply line F1 between a transformer 5 and loads L1 to Lm is provided with a coil 7. If the excess current flows to the power supply line F1 owing to a short circuit of the power supply line F1 or abnormality of the loads L1 to Lm, the coil 7 is blown out to electrically open the power supply line F1.
