1. A water-repellent particle comprising:
a particle; and
a water-repellent portion comprising a dried product of a treatment agent on a surface to be treated of the particle, wherein the water-repellent portion on a surface to be treated of the particle comprises a film-like water-repellent portion and/or a particulate water-repellent portion on a surface to be treated of the particle, the treatment agent comprising:
a condensation product of a liquid composition comprising at least one selected from the group consisting of a polysiloxane compound having a hydrolyzable functional group or a condensable functional group and a hydrolyzate of the polysiloxane compound having a hydrolyzable functional group or
a liquid composition comprising at least one selected from the group consisting of a polysiloxane compound having a hydrolyzable functional group or a condensable functional group and a hydrolyzate of the polysiloxane compound having a hydrolyzable functional group,
wherein the dried product of the treatment agent contains an aerogel formed from aerogel particles contained in the liquid composition, and the liquid composition contains aerogel particles in an amount of 0.1 to 10 parts by mass or less-per 100 parts by mass of the total amount of the liquid composition.
