Abstract
The present invention provides an electrolyte membrane formed of an ion conductive composition. Said composition contains a liquid crystalline polymer having an ionic dissociative group. Molecular chains of the liquid crystalline polymer are orientated in a specific direction. The degree of orientation α of the liquid crystalline polymer is in a range of 0.45 or more and less than 1, as defined by equation (1) as follows,Degree of orientation α=(180−Δβ)/180  (1),
