PROBLEM TO BE SOLVED: To provide a conductive particle with a projection and an anisotropic conductive material having a low connection resistance, a small variation in the conductive performance of the particle, and excellent conductivity reliability. The present invention includes resin fine particles and a coating layer provided on the outer surface of the resin fine particles and having protrusions on the surface, the protrusions having a height of 100 to 300 nm, , The amount of deformation (μm) when applying a force (F2, mN) that starts breaking of the conductive particles, including nickel and phosphorus, and the force (F1, mN) of the same numerical value as the diameter of the conductive particles Conductive particles produced according to the deformation (μm) and an anisotropic conductive material including the conductive particles are provided.
