1. A vehicle composition for inorganic fine particle dispersion, comprising a binder resin, an organic solvent, and an organic compound having a boiling point at normal pressure of 200° C. or higher and lower than 400° C.,
the binder resin containing a (meth)acrylic resin,
the (meth)acrylic resin containing a segment derived from a (meth)acrylate containing an ester substituent having a carbon number of 1 to 4 which is a linear or branched alkyl group, and a segment derived from a (meth)acrylate containing an ester substituent having a carbon number of 5 to 8 which is a linear or branched alkyl group,
the (meth)acrylic resin containing 30 to 95% by weight of the segment derived from the (meth)acrylate containing an ester substituent having a carbon number of 1 to 4,
the (meth) acrylic resin having a weight average molecular weight in terms of polystyrene of 200,000 to 3,000,000,
the organic compound containing at least one selected from the group consisting of a phenol compound, and a quinone compound, and
the amount of the organic compound being 1 to 10 parts by weight relative to 100 parts by weight of the binder resin,
wherein time required for 90% by weight decomposition of the (meth)acrylic resin during heating at 5° C./min from 30° C. is 50 minutes or less.
