The invention provides a prefabricated internal partition wallboard which comprises a wall and heat-insulation boards. The wall is made of foam concrete, the heat-insulation boards are packaged in the wall and are made of polystyrene, a concave tongue face and a convex tongue face which can be fastened with each other are respectively arranged on two side surfaces of the wall, and two rows of through holes which are uniformly distributed are formed in the surfaces of the heat-insulation boards along the length directions of the heat-insulation boards. The prefabricated internal partition wallboard has the advantages that the prefabricated internal partition wallboard is easy to mount and low in construction intensity; the wall and the surfaces of the boards are formed by means of pouring by the aid of grinding tools, accordingly, the flatness of the wall and the flatness of the surfaces of the boards are easy to guaranteed, and good appearance effects can be realized; good sound-insulation and heat-insulation effects can be realized.
