An electrophoretic particle including: a pigment particle having an average particle diameter of 1 .mu.m or smaller; and a polymer layer having an average thickness of 1 to 500 nm formed on a surface of the pigment particle, wherein 50% or higher of an entire surface of the pigment particle is coated with the polymer layer. The electrophoretic particle can be produced by radical polymerization using a polymerization initiator in a state where a pigment particle and monomer components are present in a solvent. The electrophoretic particle can be used in a microcapsule and a sheet for electrophoretic display, as well as an electrophoretic display device and an electronic equipment.
