Abstract
The present invention provides hollow particles that can suppress the occurrence of pinholes in shells and prevent the collapse of hollow portions due to deformation. The present invention specifically provides hollow particles including a shell and a hollow portion surrounded by the shell, wherein the shell contains a (meth)acrylic-based resin; wherein the hollow particles have an average particle diameter of 10 nm to 150 nm; wherein the hollow particles have a sphericity or 0.90 to 1.0; and wherein the hollow particles have a hollow ratio of 35% to 70%.
