The invention provides a wall board made of reconstituted bamboo. The wall board comprises reconstituted-bamboo wall board main bodies and connectors, wherein the connectors comprise first connectors arranged on the reconstituted-bamboo wall board main bodies and second connectors connected with the first connectors for connecting adjacent reconstituted-bamboo wall boards; each first connector comprises a sliding rod part which slides to run through the reconstituted-bamboo wall board main body in parallel, and two connecting parts respectively arranged at the two ends of the sliding rod part; and a guide sliding hole for matching with the sliding rod and for sliding of the sliding rod is formed in the reconstituted-bamboo wall board main body. The wall board provided by the invention has the advantages that the structure form of the traditional wall board is broken through, the reconstituted bamboo is adopted for the main bodies, and in the process of practical use, two adjacent reconstituted-bamboo wall boards are connected together by fastening of the second connectors and the first connectors on the two reconstituted-bamboo wall boards; and the structure is novel and reasonable, the connection of adjacent wall boards is convenient, the operation is flexible and the practicability is strong.
