The invention provides a veneer for indoor wall decoration as well as processing equipment and a manufacturing method for the veneer. The manufacturing method is characterized by comprising steps as follows: fabric is laid and absorbed on a mold surface where a plurality of suction holes connected with a negative pressure source are formed, and a veneering decorative surface layer which is consistent with the shape of the mold surface layer is formed; a veneer body is bonded on the decorative surface layer through an adhesive applied on the veneering decorative surface layer, and the decorative veneer formed by the veneer body and the decorative surface layer veneering bonded on the veneer body is formed; and at least a layer of fiber cloth reinforcement layer is laid in the adhesive applied on the decorative surface layer, so that the surface decorative veneer which meets a strength requirement is formed. The veneer for indoor wall decoration has the advantages of simplicity and convenience in manufacturing, high production efficiency, low cost, flat and smooth appearance, good appearance effect, high product quality and the like.
