PROBLEM TO BE SOLVED: To provide a relay protection circuit and a relay driving method which inhibit rush current flowing when turning on a relay from flowing into a contact of the relay while achieving inexpensive cost, space-saving, and weight-saving implementation. SOLUTION: A contact of a relay 14 and a switching device 16 are connected in parallel to each other, and current from a power supply 12 is caused to flow to the switching device 16 of switching means for a predetermined period. Thereafter, the relay 14 is turned on and the switching device 16 is turned off, thereby protecting the contact of the relay 14 from rush current instantaneously caused immediately after activating the power supply 12.
