1 - 14 . (canceled)  
   
   
       15 . A coating apparatus for forming a coating resin layer precursor layer on a substrate, said apparatus comprising: 
 spouting means for spouting a resin layer precursor against at least a substrate to be coated;    a fastening table for fastening the substrate thereon;    moving means for moving said spouting means or said fastening table in a horizontal direction;    carrying-in means for carrying-in the substrate on said fastening table; and    carrying-out means for carrying-out the substrate from said fastening table, wherein    a step (a) in that the substrate is carried on said fastening table by said carrying-in means and the substrate is fastened at said fastening table, a step (b) in that while moving said spouting means or said fastening table in a horizontal direction by said moving means, the resin layer precursor is spouted from said spouting means to apply the resin layer precursor layer onto the substrate, and a step (c) in that the substrate having the resin layer precursor layer is carried out from said fastening table to the outside by said carrying-out means are sequentially performed and, further comprising    a weir member arranged in the vicinity of edges of the substrate upon the application of the resin layer precursor onto the substrate in said step (b) so that said resin layer precursor stays in at least a pair of the edges of the substrate.    
   
   
       16 . A coating apparatus for forming a coating resin layer precursor layer on a substrate, said apparatus comprising. 
 spouting means for spouting a resin layer precursor against at least a substrate to be coated;    a fastening table for fastening the substrate thereon;    moving means for moving said spouting means or said fastening table in a horizontal direction;    carrying-in means for carrying-in the substrate on said fastening table;    carrying-out means for carrying-out the substrate from said fastening table; and    a waste liquid pan for receiving the resin layer precursor spouted from said spouting means outside the substrate, wherein    a step (a) in that the substrate is carried on said fastening table by said carrying-in means and the substrate is fastened at said fastening table, a step (b) in that while moving said spouting means or said fastening table in a horizontal direction by said moving means, the resin layer precursor is spouted from said spouting means to apply said the resin layer precursor layer onto the substrate, and a step (c) in that the substrate having the resin layer precursor layer is carried out from said fastening table to the outside by said carrying-out means are sequentially performed,    wherein said waste liquid pan is descended or lifted upon the application of the resin layer precursor onto the substrate in said step (b) so that the resin layer precursor which is spouted from said spouting means outside the substrate stays between said waste liquid pan and at least a pair edges of the substrate, where the edges of the substrate are coated with the resin layer precursor.    
   
   
       17 . The coating apparatus according to  claim 15  or  16 , wherein said fastening table is of a size which is smaller than that of the substrate.  
   
   
       18 . The coating apparatus according to  claim 15  or  16 , wherein each of said moving means, said carrying-in means and said carrying-out means is of a size which is smaller than a width of the substrate.  
   
   
       19 . The coating apparatus according to  claim 15  or  16 , wherein the substrate is a photovoltaic element.  
   
   
       20 . A coating apparatus for forming a resin layer precursor layer on a substrate, said apparatus comprising 
 a nozzle for spouting a resin layer precursor against a substrate to be coated;    a waste liquid pan having an extended gradient verge portion which receives the resin layer precursor spouted from said nozzle, said waste liquid pan being situated to oppose said nozzle;    a fastening table for fastening the substrate thereon to position between said nozzle and said waste liquid pan so that a face of the substrate to be coated is opposed to said nozzle; and    an elevator for lifting or descending at least either said waste liquid pan or said fastening table,    wherein at least either said waste liquid pan or said fastening table is moved by said elevator so that an interstice with an extent capable of allowing a certain amount of the resin layer precursor spouted from said nozzle to stay therein is formed between the gradient verge portion of said waste liquid pan and the edges of said substrate.    
   
   
       21 . The coating apparatus according to  claim 20 , wherein said fastening table is of a size which is smaller than that of the substrate.
