Abstract: PURPOSE:To obtain an integrally formed electrically conductive connection member free from short-circuiting between conductors by composing a component material with a high polymer compound, having a repetition unit of pi-electron conjugate joining, and synthetic resin or synthetic rubber, and using a specific insulation resistant value. CONSTITUTION:A component material is composed of a high polymer compound, having a repetition unit of pi-electron conjugate joining, and synthetic resin and/or synthetic rubber, and has the effect of anisotropic electric conductivity in which an electrically good conductive condition is shown when the component material has very thin thickness and high insulation property is shown in thickness over the above mentioned one. Although a value of the critical thickness differs with the kind of the component material and composition, normally is in a range of 0.2-2mum. Plural mutually-facing electrodes are integrally formed using an anisotropic electrically conductive resin component material having insulation resistance of 10<8>OMEGA or larger in a 10mum distance between electrodes and in which an insulation resistant value suddenly lowers when it is 2mum or less. Thus stable anisotropy is shown in the connection of mutual electrodes and insulation property between conductors, and a suitable connection member can be obtained in the electrode connection of a minimum pitch of 100mum pitch or less.
