PROBLEM TO BE SOLVED: To provide a single hollow particle having excellent optical diffusibility. SOLUTION: The single hollow particle comprises a vacancy, an inner polymer layer and an outer polymer layer in this order from the center toward the outside. The inner polymer layer has 50,000-400,000 weight average molecular weight (measured by GPC) and comprises a (meth)acrylate-styrene-based copolymer containing 20-70 wt.% (meth)acrylate component. The outer polymer layer comprises a copolymer derived from a monomer mixture of 10-50 wt.% crosslinkable vinyl monomer and 90-50 wt.% hydrophobic (meth)acrylate monomer.
