Abstract

The present invention provides a transparent conductive material with little change in electric resistance under influence of temperature or humidity and a transparent conductive membrane using the same.

The transparent conductive material of the present invention includes a resin, a transparent conductive particle, a silica material containing at least either of a silica particle or a precursor of silica particle, and a silane coupling agent.

Claims

1. A transparent conductive material, comprising:

a resin;

a transparent conductive particle;

a silica material comprising at least either of a silica particle or a precursor of a silica particle; and

a silane coupling agent.

2. The transparent conductive material according to claim 1, wherein the content of the silica material is 0.1 to 40% by mass relative to the total quantity of the transparent conductive particle and the silica material.

3. A transparent conductor having a transparent conductive layer comprising a cured body of the transparent conductive material according to claim 1.

4. The transparent conductor according to claim 3, comprising a substrate containing an organic compound and the transparent conductive layer provided on the substrate.
