Claim Text:
1. A conductive composition comprising: an elastomer component; a fibrous carbon material having a fiber diameter of less than 30 nm; and a flake-like carbon material having a graphite structure, having an intensity ratio (G/D ratio) of a peak (G band) appearing in the vicinity of 1580 cm the flake-like carbon material is produced from a carbon material having a graphite structure, a G/D ratio of Raman spectrum of not less than 1.8, and a ratio of the minimum length to the maximum length (minimum length/maximum length) of not more than ⅕, the content of the fibrous carbon material is not less than 5% by mass and not more than 30% by mass with respect to 100% by mass of the solid content of the conductive composition, the content of the flake-like carbon material is not less than 3% by mass and not more than 30% by mass with respect to 100% by mass of the solid content of the conductive composition, and a blend ratio of the fibrous carbon material to the flake-like carbon material is set in a range of 5:1 to 1:4 by mass.
