<P>PROBLEM TO BE SOLVED: To provide a transparent conductive member exhibiting excellent transparency and conductivity and having good appearance. <P>SOLUTION: A transparent conductive member 1 comprises: a graphene layer 2; a coloring layer 3 overlapping the graphene layer 2; and a transparent substrate 4. In the transparent conductive member 1, a first region 5 consisting of a region where the graphene layer 2, the coloring layer 3 and the substrate 4 are overlapping, and a second region 6 consisting of a region where the coloring layer 3 and the substrate 4 are overlapping but the graphene layer 2 is not overlapping are formed. Between the transparent color of the first region 5 and the transparent color of the second region 6, the difference ΔL<SP POS="POST">*</SP>of L<SP POS="POST">*</SP>, the difference Δa<SP POS="POST">*</SP>of a<SP POS="POST">*</SP>, and the difference Δb<SP POS="POST">*</SP>of b<SP POS="POST">*</SP>satisfy the relation shown by following expression (1). ä(ΔL<SP POS="POST">*</SP>)<SP POS="POST">2</SP>+(Δa<SP POS="POST">*</SP>)<SP POS="POST">2</SP>+(Δb<SP POS="POST">*</SP>)<SP POS="POST">2</SP>}<SP POS="POST">1/2</SP>≤1.2 ...(1). <P>COPYRIGHT: (C)2013,JPO&INPIT |
