The embodiment of the invention provides a vehicle body and a maglev vehicle. The car body comprises a framework, a bottom frame, a pair of side walls, an end wall and a car roof. The framework is of a frame structure made of metal profiles. The bottom frame is connected to the bottom of the framework and comprises a bottom plate, and the bottom plate is of a plate-shaped structure adopting a composite material sandwich structure; the pair of side walls is connected to the two sides of the framework in the transverse direction, each side wall comprises a side wall body, and the side wall bodies are of a plate-shaped structure of a composite material sandwich structure. The end wall is connected to the end of the framework in the longitudinal direction and is of a plate-shaped structure of a composite sandwich structure. The car roof is connected to the top of the framework and is of a plate-shaped structure of a composite material sandwich structure. The composite material sandwich structure comprises an outer skin, a sandwich core and an inner skin, the outer skin and the inner skin are both made of composite materials, and a honeycomb structure or foam is arranged in the sandwich core. By the adoption of the scheme, the weight of the vehicle body can be reduced to a large extent.
