         5 . The modification method according to  claim 4 , wherein the width of the slit is larger than the width of the part of the surface of the resin article to be modified such that an electroless plating layer is deposited. 
     
     
         6 . The modification method according to  claim 4 , wherein an region on the surface of the resin article irradiated by ultraviolet rays which come through the slit has a striped pattern. 
     
     
         7 . The modification method according to  claim 2 , wherein the UV-transmissive portion is a diffraction grating. 
     
     
         8 . The modification method according to  claim 2 , wherein the ultraviolet rays are irradiated on the surface of the resin article by scanning the surface of the resin article with ultraviolet rays having a linear irradiation area through the shielding member. 
     
     
         9 . The modification method according to  claim 1 , wherein irradiation of the ultraviolet rays is performed in an atmosphere that contains at least one of oxygen or ozone.

         12 . The modification method according to  claim 11 , wherein the further modifying treatment is to irradiate ultraviolet rays having a wavelength of 243 nm or less on a region encompassing the part of the surface of the resin article using an ultraviolet ray lamp or an ultraviolet ray LED, in an atmosphere that contains at least one of oxygen or ozone. 
     
     
         13 . The modification method according to  claim 1 , wherein the surface of the resin article includes at least one of polyolefin, polyester, polyvinyl, polycarbonate, or polyimide. 
     
     
         14 . A method for manufacturing a resin article having a plating layer, the method comprising:
