Provided is a power transmitting device which comprises: a first coil module having a first ferrite core, and a first coil wound the first ferrite core and generating a magnetic field by applying an AC power source; and a second coil module including a second coil forming the induced electromotive force by the magnetic field generated from the first coil, and a second ferrite core wound the second coil, wherein based on the magnitude of the magnetic flux density generated in the first ferrite core, the first ferrite core is shaped like a rod with 10 times or more longer in length than the width or thickness of the core. |
