MIDDLE FRAME AND ELECTRONIC DEVICE

This application provides a middle frame and an electronic device including the middle frame. The middle frame includes a flat part and a first recess part that are integrally molded, the first recess part is recessed inward relative to a first surface of the flat part to form a first groove, and an opening of the first groove is located on the first surface; the first recess part includes a bottom wall, a first side wall, and a second side wall, an orientation of the bottom wall is the same as an orientation of the first surface, the first side wall and the second side wall separately intersect the bottom wall, and the first side wall is connected to the second side wall; and an opening formed by the first side wall and the second side wall is gradually enlarged in a first direction, and in a die casting molding process of the middle frame, the first direction is parallel to a flow direction of a die casting material. A thickness of the flat part of the middle frame provided in this application is small.
