<P>PROBLEM TO BE SOLVED: To provide an electric lock system capable of providing desired feeding capacity with low loss irrespective of a margin dimension. Ž<P>SOLUTION: In this electric lock system, a primary side unit 2 arranged on a door frame 10 side is provided with a primary side coil n1 wound around a primary side core 42 and a high frequency power supply part for feeding electric power having high frequency into the primary side coil n1. A secondary side unit 3 arranged on an opening and closing door 12 side is provided with a secondary side coil n2 wound around a secondary side core 50 and a stabilizing power supply part for stabilizing the electric power having high frequency fed from the secondary side coil n2 and feeding electric power required for operating an electric lock device. The primary side core 42 is provided with a winding part 43 fixed in a door frame 10 to wind the primary side coil n1 around it and leg parts 44 formed separately from the winding part 43 to form magnetic paths between both end parts of the winding part 43 and the secondary side core 50, respectively. When locking and unlocking, a driving part drives a direct acting solenoid 27 to move each of the leg parts 44 from a position for storing each of them in the door frame 10 toward a position for protruding each of them onto the opening and closing door 12 side.
