A liquid crystalline compound and an electrolyte material in which the conductivity switches between ion conductivity and non-ion conductivity depending on changes in temperature, and thus a switching function can be obtained are proposed. The liquid crystalline compound has a columnar liquid crystal phase in which an ammonium group is linked with an alkoxyphenyl group. A structural change thereof occurs depending on changes in temperature, and the conductivity switches between ion-conducting and non-ion-conducting, and thus the switching function can be obtained.
