Claim 0:
1. A composition comprising:
a binder and
a variable thermal conductivity material satisfying a conditional expression 1,
wherein a content of said 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 said binder:

κmax/κ25≥1.2  [conditional expression 1]

wherein, κ25 represents a thermal conductivity at 25° C., and κmax represents the maximum value of a thermal conductivity at 200° C. or 500° C.,
wherein the thermal conductivity material comprises at least one oxide selected from the group consisting of
metal oxides represented by MyOz, and
composite metal oxides represented by AxMyOz,, in which
A represents at least one element selected from the group consisting of alkali metals, alkaline earth metals, Sc, Y and rare earth elements,
M represents at least one metal element selected from titanium, vanadium, manganese, cobalt, or nickel,
x, y and z each independently represent a positive number, and
wherein the thermal conductivity material comprises particles having a median diameter from 10 nm to 100 μm.
