The present invention discloses an electronic apparatus and an antenna setting method for electronic apparatus, wherein the electronic apparatus comprises a metal appearance surface; the metal appearance surface consists of a plurality of mutually separated metal pieces; an insulating piece is provided between the two adjacent metal pieces; each metal piece is provided thereon with one or more antennas, each antenna is connected with a communication module on a master chip of the electronic apparatus. The technical proposal provided by the present invention provides a solution for a multi-frequency antenna for an electronic apparatus having a metal appearance surface, the metal appearance surface of the electronic apparatus is divided into a plurality of metal pieces, these metal pieces are used directly to achieve multi-antennas, effectively utilizing the physical size of the metal pieces, solving the contradiction between an antenna body and the metal pieces in the antenna design in the prior art, reducing the design restriction of the metal pieces, achieving the visual effect that the metal appearance surface of the electronic apparatus maintains the unity, and realizing the design of the multi-frequency antenna without affecting the appearance surface integrity of the electronic apparatus.
