The invention relates to a honeycomb plate for a spacecraft. The honeycomb plate for the spacecraft comprises a skin, a honeycomb core and an embedded assembly; the embedded assembly is bonded with the honeycomb core; the honeycomb core is bonded with the skin; the embedded assembly comprises an integrated carbon fiber frame and a metal embedded piece; and the metal embedded piece is bonded in theintegrated carbon fiber frame. The integrated carbon fiber frame comprises a first U-shaped beam structure and a second U-shaped beam structure; and the opening directions of the first U-shaped beamstructure and the second U-shaped beam structure are reverse to each other. The metal embedded piece is bonded in the openings of the first U-shaped beam structure and/or the second U-shaped beam structure of the integrated carbon fiber frame. The integrated carbon fiber frame is a frame which is integrally molded by using a carbon fiber laying and/or winding mode. The honeycomb plate for the spacecraft has the advantages of multi-angle supporting, light weight, compact structure, good machining and adjusting process, high stability, high bearing capacity, good mechanical environment adaptability and so on.
