Claim:
1. A graphene composition comprising a compound, a graphene, and a dispersant, the graphene being contained in an amount of from 0.01 to 5% by weight and containing first flakes having a longer edge of less than 1 μm and second flakes having a longer edge of 1 μm or more and less than 5 μm, a number of the first flakes being 5% or more of the entire flakes in the graphene, a total number of the first flakes and the second flakes being 90% or more of the entire flakes in the graphene, 60% or more of the entire flakes in the graphene having a thickness of more than 1.3 nm and having a thickness of 100 nm or less, the compound being polymers having an average molecular weight of from 10,000 to 1,000,000, wherein the first flakes intervening into interspaces of the polymers, the second flakes connecting the polymers to each other.
