Abstract

Embodiments of the present application provide an electronic device and a method of manufacturing a housing for the electronic device, which belong to a field of electronic product. The electronic device comprises a housing and an antenna. The housing comprises N layers each of which is made of a first fiber material and a second fiber material; and the housing comprises a first region, and a second region made of the second fiber material. In the N layers, a first layer has a first fiber direction and comprises the first fiber material and the second fiber material, and a fiber direction of the first fiber material in the first layer is consistent with the first fiber direction, and a fiber direction of the second fiber material in the first layer is consistent with the first fiber direction, wherein a first splicing face where the first fiber material and the second fiber material in the first layer are spliced is parallel to the first fiber direction, and is hidden in the first layer so that when the first layer is formed as an outer surface of the housing, the housing is formed into one piece. The antenna is securely disposed in the housing and comprises a radiator in the second region, wherein a shielding influence value of the second fiber material on the radiator is less than a shielding influence value of the first fiber material on the radiator.
