A coating composition contains 5 parts by mass or more and 20 parts by mass or less (i.e., 5 to 20) of a first resin composition, 5 parts by mass or more and 20 parts by mass or less (i.e., 5 to 20) of a second resin composition, and 40 parts by mass or more and 65 parts by mass or less (i.e., 40 to 65) of an inorganic powder. The first resin composition is a poly(meth)acrylate with a glass transition temperature Tg of ≤−20° C., and the second resin composition is a compound having structures represented by general formulae (1) and (2), below, one or more structures for each. R 1 , in general formula (1), and R 2 , in general formula (2), are each independently a hydrogen atom or a methyl group. X, in general formula (2), is any substituent that is not a hydrogen atom. |
