PROBLEM TO BE SOLVED: To provide a relay control device capable of performing a sure start-up of a relay while restraining heat generation of a relay coil. SOLUTION: A control part 12 continuously keeps a first transistor SW1 on from a start of electricity conduction to the relay coil Co until an elapse of a given time period. With this, the relay coil is continuously conducted from an on-vehicle battery B. The control part 12 intermittently puts on a second transistor SW2 at least after an elapse of a given time period. With this, the relay coil Co is intermittently conducted from the on-vehicle battery B. COPYRIGHT: (C)2008,JPO&INPIT
