PROBLEM TO BE SOLVED: To provide a resin particle excellent in stability and small in the variation of deformability due to the variation of temperature.SOLUTION: The resin particle is formed of a resin having 35% or less of a hysteresis loss when compressed into 30% of an initial state at room temperature and 10 or less of a variation rate of complex viscosity (a complex viscosity value at -20°C/a complex viscosity value at 100°C) obtained by dynamic viscoelasticity measurement and resulting from a measurement temperature variation from -20°C to 100°C. The resin particle can be preferably used as spacer particles for resin composition layers added in a resin composition layer in order to control the thickness of the resin composition layer. |
