An electronic device and a heat dissipation plate are provided. The electronic device includes a frame or a housing, a first heat generating component, a second heat generating component and a heat pipe, and the heat dissipation plate includes the frame and the heat pipe. The heat pipe is installed at the frame or housing and has branches. An orthogonal projection of the heat pipe on the frame or the housing overlaps at least part of orthogonal projections of the first heat generating component and the second heat generating component on the frame or the housing.
