PROBLEM TO BE SOLVED: To provide conductive particles and an anisotropic conductive material capable of enhancing connection reliability when used in electrical connection between the electrodes.SOLUTION: Conductive particles 1, 11, 21 include, respectively, a base material particle 2, and a solder layer 4, 22 arranged on the surface 2a of the base material particle 2. In the conductive particles 1, 11, 21, the grain aggregate in the solder layer 4, 22 is larger on the outer surface side than on the inner surface side of the solder layer 4, 22 in the thickness direction, or larger on the inner surface side than on the outer surface side of the solder layer 4, 22 in the thickness direction. The anisotropic conductive material contains the conductive particles 1, 11, 21, and a binder resin. |
