Abstract
In a conductive urethane composition including polyurethane obtained by a poly-addition reaction of polyol and polyisocyanate, polyether polyol is used as the polyol. An average value of a non-saturation degree of the polyether polyol is set to not more than 0.025 milliequivalents/g. The conductive urethane composition contains an organic ionic-conductive agent such as organometallic salts having fluoro groups and/or sulfonyl groups.
