A microstructure that comprises an insulating base material having through micropores filled with metal at a high filling ratio and that can be used as an anisotropically conductive member is provided. The microstructure comprises an insulating base material having through micropores with a pore size of from 10 to 500 nm at a density of from 1×106 to 1×1010 pores/mm2, a metal being filled into the through micropores at a filling ratio of at least 80%. |
