Abstract
A light-reflective conductive particle for an anisotropic conductive adhesive used for anisotropic conductive connection of a light-emitting element to a wiring board includes a core particle coated with a metal material and a light-reflecting layer formed from light-reflective inorganic particles having a refractive index of 1.52 or more on a surface of the core particle. Examples of the light-reflective inorganic particles having a refractive index of 1.52 or more include titanium oxide particles, zinc oxide particles, or aluminum oxide particles.
