1. A coating liquid comprising:
an aerogel particle;
a liquid medium;
a first binder resin, wherein the first binder resin is a cellulose-based resin;
a second binder resin soluble in the liquid medium, wherein the second binder resin is an epoxy resin, the second binder resin having lower solubility in the liquid medium than the first binder resin, wherein a content of the second binder resin is over 100 parts by mass and 600 parts by mass or less with respect to 100 parts by mass of the first binder resin; and
