The present disclosure provides a terminal housing and a terminal, belonging to the field of communication technology. The terminal shell comprises a rear cover, a radio frequency module and an antenna array, wherein the radio frequency module is connected with the antenna array. The rear cover includes a first region and a second region other than the first region, the first region being connected to the second region by an insulating material. The first area comprises a plurality of antenna array elements, each antenna array element is made of a conductive material, and any two adjacent antenna array elements are connected through an insulating material, so that a plurality of antenna array elements form an antenna array. A design scheme of an antenna array is proposed, the antenna arrayis located on the terminal housing. The back cover is not covered by the back cover, the signal can be received and transmitted directly, the signal of the antenna array is avoided to be shielded andshielded because the back cover is made of a metal material, the performance of the antenna array is guaranteed, the limitation that the back cover can only be made of a non-metal material is eliminated, the application range is wider, and the flexibility is improved.
