Disclosed is a wireless power transmission pad configured to transmit wireless power to a reception pad that comprises a secondary coil. The wireless power transmission pad comprises: a primary coil arranged to surround the central space; ferrite for magnetic-coupling with the primary coil; and a housing for supporting the primary coil and the ferrite, wherein the primary coil is formed such that a flat wire having a vertical type structure, in which the long axis of a cross section is parallel to the central axis of the primary coil, is wound multiple times.
