PROBLEM TO BE SOLVED: To provide an electrical connector capable of surely stably ensuring electrical continuity, even if compression load is small. SOLUTION: Through-holes 1a are installed formed in a line in the length and width directions in an insulation sheet 1 serving as a base material for the electrical connector 10, and a through-hole electrode 1b, on which a gold plated layer 4 is formed, is formed on the surface the inside which a conductive paste 3 is filled. A hemispherical elastic body 2 is arranged, so as to cover the through-hole electrodes 1b on both surfaces. A large amount of conductive fine particles 2a are included in the elastic body 2. When interposed between upper and lower electrodes of an electronic component and a circuit board, the elastic body 2 is bent and pressure contacted with the upper and lower electrodes to establish electrical continuity.
