PROBLEM TO BE SOLVED: To provide a conductive rubber sheet having elasticity to be electrically connected with a surface mounted LSI and an electronic circuit board, a connector using it, and an electrical inspection jig for the circuit board. SOLUTION: This conductive rubber sheet, in which an insulation part 4 comprising an electrical insulating material and anisotropic conductive sheets 1, 2 formed from a plurality of conductive parts 3 obtained by blending conductive particles in the electrical insulating material are disposed at the position where the conductive parts overlaps each other so as to bring them into an electrically conductive state, and is formed so that the area of the surface of at least one conductive part of the anisotropic conductive rubber sheet on the one surface side of the conductive sheet becomes larger than the area of the surface of the conductive part disposed at the corresponding position of the anisotropic conductive rubber sheet on the other surface side of the conductive rubber sheet. A circuit board as an intermediate layer is formed between the anisotropic conductive rubber sheets, and the conductive rubber sheet in a laminated state of two or more layers and the circuit board as the intermediate layer are integrated.
