PROBLEM TO BE SOLVED: To provide an electroconductive minute particle capable of enhancing the reliability of an electric connection in a pressure bonding, an electroconductive material, an anisotropic electroconductive film, and a polymer minute particle. SOLUTION: This electroconductive minute particle 110 generates a crack 100K when crushed by compressing sandwiched between an upper and a lower surfaces and the crack 100K generates along the vertical direction, and a part of the upper metal layer 112 is in contact with the upper surface keeping a condition of being attached to the polymer minute particle 100 even after the crushing, and a part of the lower metal layer 113 is in contact with the lower surface keeping a condition of being attached to the polymer minute particle 100 even after the crushing. Further, a part of the side metal layer 114 keeps a shape of connecting the upper metal layer 112 which contacts the upper surface and the lower metal layer 113 which contacts the lower surface even after the crushing.
