1. A non-ohmic composition comprising a base elastomer and a plurality of non-ohmic particles,
wherein, in a case of comparing volume resistivities p of the non-ohmic composition within a range of E≥Eth for the non-ohmic composition not elongated,
the E being an electric field strength applied to the non-ohmic composition,
the ρ being the volume resistivity of the non-ohmic composition, and
the Eth being a threshold electric field strength at a point where an absolute value of a variation in a slope of log p with respect to log E is maximum,
the volume resistivity ρ for the non-ohmic composition uniaxially elongated by 50% is 50 times or less the volume resistivity ρ for the non-ohmic composition not elongated.
