Abstract

Provided is a glass sheet (1) with a film, including a laminated film (2), which includes a plurality of films laminated together, formed on a glass sheet (3). The laminated film (2) includes: an inorganic material film (4), which contains at least a noble metal, formed on the glass sheet (3); a plated metal film (5) formed on the inorganic material film; and a metal film (6) formed on the plated metal film (5). The laminated film (2) is black when viewed from a glass sheet (3) side.

First claim

The invention claimed is:

1. A glass sheet with a film, comprising a laminated film, which includes a plurality of films laminated together, formed on a glass sheet,
wherein the laminated film includes an inorganic material film, which contains at least a noble metal, formed on a non-reformed surface of the glass sheet, and a plated metal film formed on the inorganic material film, and
wherein the laminated film is black when viewed from a glass sheet side.

2. The glass sheet with a film according to claim 1 , wherein the plated metal film is formed by electroless plating.

3. The glass sheet with a film according claim 2 , wherein the laminated film further includes a metal film formed by electroplating on the plated metal film.

4. The glass sheet with a film according to claim 2 , wherein the plated metal film formed by electroless plating is formed of copper or nickel.

5. The glass sheet with a film according to claim 1 , wherein the glass sheet has a thickness of 300 μm or less.

6. The glass sheet with a film according to claim 1 , wherein the laminated film is processed to have a shape of an electrode for a touch sensor.

7. A touch sensor, comprising the glass sheet with a film of claim 6 .

8. A film, comprising:
an inorganic material film, which contains at least a noble metal, formed on a non-reformed surface of a glass sheet; and
a plated metal film formed on the inorganic material film,
wherein the film is black when viewed from a glass sheet side.

9. A method of producing a glass sheet with a film, comprising forming a laminated film, which includes a plurality of films laminated together, on a glass sheet,
wherein the forming of the laminated film comprises:
forming an inorganic material film, which contains at least a noble metal, on a non-reformed surface of the glass sheet; and
forming a plated metal film on the inorganic material film,

wherein the laminated film is black when viewed from a glass sheet side.
