Abstract
A crystalline Ni alloy particle for an anisotropic conductive film comprising Ni and a metalloid element such as P, B, etc. and having a structure in which a Ni intermetallic compound phase is precipitated can be produced by preparing substantially amorphous Ni alloy particle by an electroless reduction method, and heat-treating the substantially amorphous Ni alloy particle. The Ni alloy particle is preferably heat-treated after disintegration, and preferably coated with Au.
