To provide hollow particles having a high void ratio and excellent pressure resistance. Hollow particles which comprise a shell containing a resin and a hollow portion surrounded by the shell, wherein a void ratio is 60% or more; wherein a volume average particle diameter is from 10 μm to 50 μm; wherein the shell contains, as the resin, a polymer in which from 70 parts by mass to 100 parts by mass of a crosslinkable monomer unit is contained in 100 parts by mass of all monomer units, and the crosslinkable monomer unit contains a bifunctional crosslinkable monomer unit derived from a bifunctional crosslinkable monomer and a trifunctional or higher-functional crosslinkable monomer unit derived from a trifunctional or higher-functional crosslinkable monomer; and wherein, when observed in plan view, a percentage of particles having a dent with a size of 5% to 50% of the particle diameter, is 10% or less.
