<p>The present invention relates to a coil type unit for wireless power transmission, a wireless power transmission device, an electronic device, and a method of manufacturing a coil type unit for wireless power transmission. The coil type unit for wireless power transmission according to the present invention includes a coil pattern of a line pattern shape; a magnetic part which has a side attached to the coil pattern; and a bonding part which is interposed between the magnetic part and the coil pattern and mutually bonds the magnetic part the coil pattern. The magnetic part is formed by performing a sintering process after at least one magnetic sheet and at least one conductive sheet are stacked. The magnetic part has a conductive hole which electrically connects both ends of the coil pattern and the conductive sheet, in a position where both ends of the coil pattern are arranged.</p> |
