2 . The sheet material according to claim 1 , wherein an average value of respective longest diameters of the first electroless plating films is 18 to 90 nm when the one main surface of the resin layer is viewed in a planar view from the side of the electroless plating film.

3 . The sheet material according to claim 1 , wherein an area ratio of the first electroless plating films to the one main surface of the resin layer is 80 to 99% when the one main surface is viewed in a planar view from the side of the electroless plating film.

4 . The sheet material according to claim 1 , wherein a main surface, on the opposite side to the first electroless plating films, of the second electroless plating film is a rough surface.

5 . A method for manufacturing a sheet material, comprising:
a step of forming a resin layer comprising a binder and a plurality of polypyrrole particles on a transparent base material, at least some of the plurality of polypyrrole particles respectively having exposure surfaces exposed from one main surface of the resin layer, the plurality of exposure surfaces being scattered on the one main surface of the resin layer, and the transparent base material being provided on the side of the other main surface of the resin layer; a step of making a solution comprising a catalyst contact the exposure surfaces of the polypyrrole particles, to form catalyst nuclei respectively adhering to the plurality of exposure surfaces; a step of forming first electroless plating films on the one main surface of the resin layer to respectively surround the plurality of exposure surfaces and the catalyst nuclei; and a step of forming a second electroless plating film to cover the first electroless plating films, a main surface, on the side of the first electroless plating films, of the second electroless plating film forming concave portions, respectively, along surfaces of the first electroless plating films.

6 . A method for manufacturing a metal mesh, comprising a step of performing etching for the electroless plating film in the sheet material according to claim 1 to form an electroless plating film having a mesh-shaped pattern.

7 . A metal mesh comprising:
a resin layer comprising a binder and a plurality of polypyrrole particles; an electroless plating film provided to form a mesh-shaped pattern on the side of one main surface of the resin layer and comprising first electroless plating films and a second electroless plating film; and a transparent base material provided on the side of the other main surface of the resin layer, wherein at least some of the plurality of polypyrrole particles respectively have exposure surfaces exposed from the one main surface of the resin layer, and the plurality of exposure surfaces are scattered on the one main surface of the resin layer, the first electroless plating films are provided on the one main surface of the resin layer to respectively surround the plurality of exposure surfaces of the polypyrrole particles, and the second electroless plating film is provided to cover the first electroless plating films, and a main surface, on the side of the first electroless plating films, of the second electroless plating film forms concave portions, respectively, along surfaces of the first electroless plating films.

8 . A metal mesh comprising:
a transparent base material; a resin layer provided to form a mesh-shaped pattern on the transparent base material and comprising a binder and a plurality of polypyrrole particles; and an electroless plating film provided on the transparent base material along the mesh-shaped pattern of the resin layer while covering the resin layer and comprising first electroless plating films and a second electroless plating film, wherein at least some of the plurality of polypyrrole particles respectively have exposure surfaces exposed from a surface of the resin layer, and the plurality of exposure surfaces are scattered on the surface of the resin layer, the first electroless plating films are provided on the surface of the resin layer to respectively surround the plurality of exposure surfaces of the polypyrrole particles, and the second electroless plating film is provided to cover the first electroless plating films, and a surface, on the side of the first electroless plating films, of the second electroless plating film forms concave portions, respectively, along surfaces of the first electroless plating films.
