A composition including a binder and a variable thermal conductivity material satisfying a conditional expression 1, wherein a content of the variable thermal conductivity material is from 300 parts by weight to 10,000 parts by weight with respect to a content of 100 parts by weight of the binder: κ max / κ 25 ≥ 1.2 (wherein, κ 25 represents a thermal conductivity at 25°C, and κ max represents the maximum value of a thermal conductivity at 200°C or 500°C.) |
