PROBLEM TO BE SOLVED: To obtain a function such as an antifouling properties, low adsorptivity, alkali resistant cleanability or the like by covering a surface with a functional resin layer. SOLUTION: Either an inner surface or an outer surface or both surfaces of a container is covered with a functional resin layer. As the functional resin, a silicone or fluorine resin having an alkali resistant cleanability, low adsorptivity, antifouling properties, a liquid crystal polymer having an alkali resistant cleanability, low adsorptivity, gas barrier properties, a polyolefin resin or a resin such as a polyethylene naphthalate having an alkali resistant cleanability is used. They are laminated to incorporate a function such as the anti-fouling properties, alkali resistant cleanability, low adsorptivity or the like in the container. Since the functional improvement of the container is different depending upon the resin to be formed, characteristics of the resin are utilized to design the container. Thus, the function such as the anti-fouling properties, alkali resistant cleanability, low adsorptivity or the like can be simply incorporated in the container at a low cost.
