CONDUCTIVE PARTICULATE, AND ANISOTROPIC CONDUCTIVE MATERIAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a conductive particulate which enables the formation of an adequate indentation and allows a good connecting condition to be kept when electrically connecting an object to be connected while being a fine conductive particulate.

SOLUTION: The conductive particulate comprises: a base material composed of a resin particle; and at least one conductive metal layer formed on the surface of the base material. The resin particle has an average particle size of 1.0-2.5 μm. The compression modulus (10% K value) when the diameter of the resin particle is displaced by 10% is 10,000 N/mm2or larger. The load value (breaking point load) when the resin particle is broken, and the average particle size of the resin particle satisfy the following expression: Breaking point load (mN)/Average particle size (μm)≥4.
