A metal mold for molding a lens cover can be provided without increasing the size of the metal mold or the production costs so as to prevent deterioration of production efficiency while also preventing any unfilled area or a thin thickness portion of a resin material from being formed in a final product. Also provided is a method for producing a lens cover utilizing such a metal mold. The metal mold can have a stationary mold, a movable mold and a slidable mold between them. A cavity for molding a lens sealing portion can be formed between the stationary mold and the movable mold, and the slidable mold can have a projection portion projecting into the cavity.
