Abstract: The present disclosure relates to a charging assembly of a mobile terminal. Disclosed is a charging assembly of a mobile terminal, comprising: a charger; and a mobile terminal. The charger comprises: an upper case forming a top surface and a side surface; and a lower case, coupled to the lower portion of the upper case, for forming an inner space in which parts are embedded. The mobile terminal is seated in the charger and chargeable by being electrically connected to the charger. In a plurality of areas within the inner space, magnetic elements are arranged, and in the mobile terminal, a metal member is arranged in such a manner that at least a part thereof is arranged in an area which overlaps or is adjacent to the magnetic element so that the metal member is attached to the magnetic element due to attraction with the magnetic element. The top surface comprises: an inclined portion which is bent downward so as to be in contact with the rear edge portion of the mobile terminal; and a flat base portion which extends from the inclined portion and is in contact with the rear central portion of the mobile terminal, wherein the magnetic elements arranged in the plurality of areas are placed diagonally to each other.
