Abstract
Spacer particles for a resin composition layer have a compressive strength at 10% compressive deformation (10% compressive strength) at room temperature (rt) of 0.05 to 10 MPa, have a rate of change in 10% compressive strength-by a temperature change from rt to 50° C. of 5% or less or have a rate of change in 10% compressive strength by a temperature change from −20° C. to rt of 30% or less, and have a volume average particle diameter of 2 to 200 μm and a coefficient of variation in particle diameter of 15% or less.
