PROBLEM TO BE SOLVED: To obtain high performance, long reliability, and superior safety by employing a fusion salt material made of a lithium salt and a pyridium based compound as an electrolyte of an electrochemical device such as battery and electric double-layer capacitor or the like. SOLUTION: This fusion salt material is made of a lithium halide or per- chloride salt and the like and a pyridium based compound having an ion isolation group, making a uniform, non-crystal mixing state. This material is liquid or viscous elastic body at room temperature or a temperature range slightly higher than the room temperature and has high conductivity by degree of many carrier-ion and high ion movement. In particular, since alkyl pyridium tetra boride is liquid in a room temperature range, its use is preferable.
